Your opinion might be unpopular but it shouldn't be. I'm quite well off, have friends, an overall good life, but at the same time was a miserable sack of shit.
Until I talked to a therapist. Initially we spoke every week, now I talk to her about once a month. We talk about everything. What bothers me at work. What bothers me in the world. Things that are going well. Things that are unfair. And she's an impartial advisor on how I can handle and deal with my feelings.
Going to a therapist has turned my life around for the better, and I feel dumb for not going earlier.
If we break our bones we visit a doctor. If our teeth hurt we visit a dentist. And similarly when we feel depressed we should talk to a therapist.
I hope OP finds the help he needs.
