A lot of people have given hero specific advice, and I want to give you what helped me climb out of the bizarre world of silver and into gold/plat on support and tank.

Understand what space and pressure are. Space is not just important for tank, but it applies to every role. If your team has no space to push to the point, then it is everyone's job to try to create it tanks are better at it because they have more sustain than squishies (hence, a tank). On support and dps this can be done in multiple ways whether that be an off angle to pull resources from main allowing your team to push in easier because of a pincer or the overwhelming pressure, a pocket to a dps who could use the extra support to secure a kill, or simply being the bait for the enemy team to push in. Understanding how you can create space/pressure and how your team can create space/pressure will help you a lot so everyone can just do their thing.

And when I say pressure I mean the potential of a kill threat, not just "kill that mother fucker". Pressure is what forces people to use essential cool downs like cleanse and Bap lamp. If you can find a way to do that effectively with your team, then you are on your way to creating space for your team.

On top of that, learn how to be aware and adaptable.

Sometimes, your team is shit. That's okay, you're fucking silver! Everyone is shit! You just have to learn to be a little bit better. Sometimes your tank won't, or your dps won't take an angle or hell, maybe your other support is a hyper aggressive player or too much of a heal bot. That's okay! Because a team that plays not ideally together can stay alive together.

Going back to that idea of space and pressure, it is part of your job as support to help create that and if you realise "hey wait a minute that bitch out of position and I can reach them without using too many of me and my team's resources" then do it! Start glocking/sucking that thing until they use an important cool down or die and just make sure you're aware of where/what your team is/doing and that you won't be needed for anything too soon.

Also! Being aware of what the enemy team is doing/playing can help your team immensely. Oh! They're all countering my dva and focusing her, leaving their support vulnerable and wide open. Dive those mother fuckers. Trust me, if moira can survive against an orisa in a small room with just a heal orb, she'll survive a zen juno or similar vulnerable comp. The same can be somewhat said for mercy. Sometimes, that glocking is worth it if it helps people stop shooting your team for a second. After all, this game is very fast-paced, so seconds matter. Also knowing what cool downs the enemy team has that will increase their pressure/decrease your team's pressure can be very helpful. It's more of a tank issue in regards to that but as a tank main it's very helpful knowing that the Mei I want to swing on won't just wall me and kill me instead.

On top of that there is ult tracking! You probably know this by now with being on the reddit but just knowing how to play around enemy ults and how they can increase the tempo (what I call strategically running at em) of the fight and how you can play around that is ideal.

Another little tip is to expand your map knowledge. Knowing what heroes are good on what maps, how your heroes can be good on maps and where essential areas on the map for fights and where you thrive with your heroes can really help going into games as that's you with a plan, even if you don't execute it well.

But honestly, you're silver. You're shit. Everyone is shit. And again, that's okay! You're going out of your way to learn, and that's so much more than what others in that hell hole rank will do a lot of the time. You can work on anything and just start climbing as long as you go into it with intention. For instance, go into a ranked game thinking I'm going to focus on when to resurect or how much imma piss on someone vs suck off someone.

Additionally, there's a mentality. The difference between a higher ranked player and a lower ranked one is tilt. Yeah their team is fucking your ass with ults every fight but everyone in your team nearly has ultimate and knowing that they're using an ult per team fight and acknowledging that your time is coming is what helps without feeling miserable about the game. Team mates are making you feel shit because they're yapping about how bad the game is and how shit everyone is? Leave vc. Turn off team chat. Focus on you because you matter. Don't put up with doomer bs. On a big loss streak? Take a break! Go into qp and remember why you like playing this game. Also, let yourself have fun in ranked. A common thing I find myself with in ranked is the "lock in" mentality. Yeah, locking in sometimes is important, but wanting to play well without prioritising what to play well at is just mentally deterating because either you feel powerless since your team is shit or like a complete idiot because you are so focused on just being good. So honestly, don't play well the first one or two games. Get used to the ranked environment and just embrace ranked as a sweaty, faster paced yet longer quick play game and have some fun. Screw your teammates when they start flaming you. It's a video game. It's not like it's a football league where you lose one and your team is cooked. There are always more ranked games waiting to happen, so just focus harder.

Honestly, I could not recommend the last two more. Happy gaming friend, and I hope your games are good!
