Try and think about what makes you happy. It's a start. Waiting for inspiration and purpose is a hard thing, finding it is even harder. But, if you do things you like and wait, at some point a door will open.
This sounds like your average 20YO crisis, congratulations clearing the levels so far. Don't worry, university is there to crush all the dreams you had and make you feel insignificant, this means you're no longer a baby. What you need now is a bit of epicureism and good sense of humour, so keep trying and failing as much as you can. I am always here to coach you in your existential moments, I can't have our ex-cultist leader thinking virtual life is more rewarding than real one.
If you don't feel good about the future direction of your life you can think things through & change. Or maybe i misinterpreted. Hope you have some friends to share your worries. Wishing the best for you.
Thanks for your advice, guys!! I like helping people so I've decided to take my out a bit and work in a NGO as a volunteer until I find a part-time job!!!
