Is there a source for your signature gif?I'm working through it right now.
Even when life is going really well, you feel utter despair. So weird.
I think that I'm mostly through it. Mixture of losing my faith, existential crisis, random bursts of anger, feeling completely unloved...
What has helped most is having people to talk to. To help you get through difficult feelings.
What I did most was deep thinking and rationalization. This sort of dangerous, cause it's not that far off from falling into those depressive thoughts. Just think through and find what is bothering you and try to deal with it.
It's not really a bad thing though, as long as you make it through. It helps you to grow as a person, find what really matters and has meaning in your life. Get over some fears and anxieties, slowly but surely I guess. Having people make you do things you enjoy is good as well. Help you get past things that you feel are holding you back.
Anyways I hope I helped, somewhat. This is just subjective experience, but maybe you can find some commonality.
I would also be very curious to know what others have to say on the matter, help is still needed somewhat on my part, if you feel like it.
