OK, a few things:

1. You're a decent guitarist based on that zeppelin thing you posted. Keep practicing. I've been playing for about 20 years and I can tell you that consistent practice (30-60 minutes a day minimum with intense longer sessions to target specific techniques once in a while) will lead to being "great", which can be pretty awesome if you play it right.

2. Please don't say "help me get discovered", this is not how it works. If you want to make a living as a musician, you will need to constantly work to gain exposure and keep your listeners interested. Very few musicians ever reach a point where they can "coast" based on their level of success. You have the advantage of already having adapted to non-traditional living situations, so going on tour, crashing on couches, etc. should be easier for you than those of us who are spoiled in our comfort bubbles. Speaking of which, PLAY IN FRONT OF PEOPLE EVERY CHANCE YOU GET. The more you do it, the easier it gets. The worst tragedy is someone who has talent, gets "discovered" and then chokes in front of huge audience because they didn't go through the steps that confident performers go through.

3. Your nose isn't that big, to my mind you're more attractive than the average 22 yr old. Most likely you get bullied simply because you're thoughtful, creative, etc and don't conform to local standards. If that's the case, consider moving to somewhere where everyone isn't a giant d-bag. I know it's hard when you have no money, experience, etc. But there are cities in North America where jobs are plentiful. Consider six or twelve months of living somewhere just to save up some money and move somewhere else where you can play.

4. check out r/depression- they will help and support you. My girlfriend is clinically depressed and is on all kinds of medications so I know how hard it is, you can't "talk yourself out of it" or suck it up. But r/depression is full of people who are coping, and that is what you need help with.
