i was the same, only thing i was good at was drawing.
very few friends and no life but there's always something you can do that will give your life a meaning.
for me it was bodybuilding, i liked it because it's a solitary effort so only person i relied on was myself.

things like that, music, martial arts etc you can do all those things on your own and will grow in all of them the more time you dedicate.

one thing that is a benefit of being alone is the time we can dedicate to a passion.
find something that has appealed to you from a young age, something that you've always wanted to do or achieve even if you forgot about it in recent times.
from that you can grow by dedicating time to it.

i literally just bought a keyboard piano when i was a teen and watched youtube tutorials, from that i learnt to play.
same with bodybuilding, took some old rusted plates and bars from a friend and just trained at home to build a foundation.

maybe you could do something similar that interests you.
