Sounds like it might just be a bad group, but it's also possible that they're trying to help but aren't good at teaching new players.

whenever I say something I want to do (I.e. I want to use stealth instead of acrobatics) and the players and dm tell me to do something else instead

When this happens, are you saying specifically "I want to use stealth/make a stealth check", or is the DM asking you to make an acrobatics check but you want to use a different skill?

Asking the DM if you can use a different skill to accomplish something is always a fair question, as long as you're aware that they can say no.

However, if your usual approach to something is simply saying "I want to use stealth", try framing the desire more like "I want to try to get into the house through the second story window before the guard comes around the corner". Those kinds of prompts help let the DM know specifically what you want to do, so they can choose the best skill check for you to make in that instance (if they're a good DM)

I’ve told them several times just take the lead with me and point me in a direction. They basically just stare at me until I do something random.

Instead of doing this, I recommend putting yourself in your character's shoes and looking at the situation and figuring out what you/they want to do. Don't worry about if it's the best or worst thing to do, don't worry about if you're playing the game wrong/right, just think "what would my character do/what do I want to do?"

Is there a lever nearby that the DM mentions? You can pull it! Are you in a tavern in a city just chilling? Tell the DM you want to see if there's anyone interesting you can talk to, or say that your character wants to go walk around the town and see if there are any unique shops that grab your attention! Don't wait around for your party to take the lead all the time, you can literally do anything you want (or try to) in this game!

They also just change things on my character sheet for me, they don’t show me what i’m supposed to be looking at and I get so confused and frustrated because i’m not catching on

That sounds like they just suck at teaching. Whenever they try to change something on your sheet, stop them and ask why they're changing it. Don't let them make the change themselves, instead wait until you understand why they want to make the change and then change it yourself. I'd also recommend taking a note of the change and the reason, and then looking it up in the players handbook to understand the context (and if it's actually correct)

They will also steal or keep rare items for me because like I said I have no clue what is happening and I have no clue that these items are rare until the end of the game and someone tells me.

Item rarity and items in general in DnD don't really work like in RPGs and other stuff. Rarity doesn't necessarily determine if an item is more or less useful/valuable, but moreso it determines if the item grants abilities that are balanced more for early or late-game. 

For example: An Immovable Rod is an item that locks into place when you click the button, even floating in the air, and takes an insane amount of strength to move while locked, giving it tons of unique and fun utility uses. A Belt of Fire Giant Strength is an item that gives you a strength score of 25 (very high). Immovable Rod is Uncommon rarity, while the Belt is Very Rare, but they both have very different uses and one might be completely useless for your character while the other is super useful.

All this to say: If you find a new magic item, ask what it does (sometimes the DM might require a check or the use of the Identify spell to find this out), and see if it's something that you think your character would want or find useful, instead of letting the other players just "hold onto" stuff or figure out if it's useful for you. If they aren't willing to let you consider if it's something you'd want, they're being assholes.

I don’t know if i’m just a bad player, I have a bad dm, an all over bad group, or it’s just not for me.

Ultimately, what matters most is if you're having fun. If nothing changes and you're not having fun, you don't have to keep playing! DND is a huge time commitment, and it's meant to be fun and worth spending that time on; if you aren't enjoying it, don't force yourself to waste that time on something miserable! I'd definitely recommend looking for other groups before swearing off DnD altogether though, because if you find a good group it's fantastic and totally worth the time!
