I understand you, before, it used to be a necessity for me to be alone and social disruption caused me problems.
Now it’s much better, but sometimes I’m afraid to go back to the time. Now I understand that mental health is the most important, and I try to work on myself all the time, walk a lot in the fresh air, for me it is the best way to feel good and happy.
Of course, there're difficult times, when I withdraw into myself and don't contact with others, I read a lot about mental health, I like articles on this resource https://studydriver.com/drug-abuse/ Sometimes I find a little depressive material to understand what happens much harder and worse and people cope with it, and that my problems are not so global. It always reminds me that we need to be grateful for everything and appreciate what we have.
Take care yourself
Raymond.
