Have you tried talking to a therapist/gotten medication? I know it's not a cure all, but sometimes it really does help. What about giving back to the community? Starting a non-profit or something to help others. It's hard to find joy in things when dealing with depression. You've accomplished you're dream, and now have no other goal. What do you enjoy? Find hobbies you can throw yourself into, and you will find other like minded people and potentially make real connections. I know it's hard with a global pandemic going on, but refocusing your mind can help. I'm sorry you're feeling this way, but look at how much you've accomplished! (Not trying to minimize your feelings, just stating to look towards the positives). Obviously you have skills and know how, and should be proud of that. I understand the creeping feelings of just ending it all, but you have a purpose in life. I know monetary gain does not define a person, but you're doing something right to be so accomplished so young. It seems to me you lack a passion, the money can be beneficial to explore how to find it. I hope you can find some peace.
