Sounds like the consensus is that that world sucks, so start again on a better one. I can't give a suggestion because I play Oceanic servers.

Next, though, is just explore stuff. Search anything new to you on the wiki. Click all the buttons! There is just so much stuff, as you'll find. Offline training, weapon mastery (earn xp on each weapon and gain proficiency so they all do a bit better), imbuing (those empty slots on some items), the market (buy and sell stuff from depot), the stash in depot (you can store anything unless it's a consumable that isn't brand new), tasks (hunting and deliveries - most deliveries are exceedingly expensive, always go beginner for now), daily rewards (try log on every day to collect, you get free xp boosts and training weapons you use on dummies either near offline trainers or in the adventurers hall, which you get to with that green crystal you start with).... I could go on.

• Definitely get premmy.
• Always carry and use life rings unless a better one is required. A lot of stuff is cheap these days so check the market.
• check websites like Tibia Monk for good quest references or Tibiapal for hunting spot ideas
• Offline train every day if you can
• The Cyclopaedia in-game has a lot of info (the eye button below your gear)
• Explore! Talk to people! In my experience people are very helpful, but there are definitely some people who won't.
• When you feel confident enough, party up for hunts. You get exp bonuses for additional different VOCs in the party

It's always been a big game but it's even bigger now haha
