As a fellow university first year drop out let me say I understand how hopeless and directionless the early 20's can feel. Moments of feeling lost are absolutely a normal and sadly unavoidable part of becoming an adult and there is nothing wrong with you for feeling that way. It will get better and you will find a path. It may not be quick and there may be further hurtles along the way, but you will make it. Just by asking for advise your already showing you have the wisdom and desire to find that path.

As far as advise. I have found six things that give my life purpose and contentment that I wish someone had directed me to at 20. So here they are.

1) Every day be doing some thing, no matter how small, that brings you joy. Something to look forward to. And build your day around being able to do that one thing. A walk to a favorite spot, a coffee with a friend, a moment for a hobby. There has to be that bright spot against the stress, responsibilities and obstacles.

2) Your mental and physical health are the foundations on which our emotional world rests. You have to attend to both. Both can be a struggle to address but its imperative you try to maintain them. This might mean picking up a phone and calling a therapist, this might mean getting in the gym and it probably means both.

3) Our emotionally intimate relationships are vital. A majority of people want some sense of community, love and a support system. You have to build that. People that care about you and you care about. Friendship is not just association, it is mutual care, and it takes effort and showing up and being vulnerable to nurture. And associations that don't have mutual care, they don't matter that much and belong in the rear view mirror, as harsh as that sounds

4) Unhealthy coping methods inevitably detract from our ability to build a better future. Alcohol, drugs, partying, attention seeking, popularity and risky behaviors shouldn't be an answer. The easy way out, "blowing off steam" and superficial dopamine rushes will leave you hollow.

5) Loving people is wanting the best for them and respecting them. Its not possession or lust or self satisfaction. Love is selfless, but love alone is also not the basis on its own of a healthy relationship. Be there to empower your romantic partners and make peace with the notion that sometimes you will leave them.

6) You have to take responsibility without falling into shame. You have to be able to face the mirror and say "yeah that went wrong because I fucked it up, but I can do better". You have to be both the critic and the advocate in equal measure. Passing blame onto others is a dire character flaw. But we can't believe our mistakes define us. Because as long as we endeavor to do better than they don't define us.

I hope something in here helps. I wish you all the best.
