I used to think that I was the only one who was depressed, the only one suffering from crippling social anxiety, and I would look around and be jealous of everyone else who was "normal" and obviously couldn't understand what I was feeling, and how everyone else just flitted through life so easily and how unfair it all was.
This was of course massively incorrect and very self-centered.
I sought therapy, finally, when I started imagining solving my problem by crashing my car into a tree, and was medicated and learned that despite my issues, I am responsible for how I deal with me, and EVERYONE ELSE has their own unique difficulties, even those who don't appear to. Also that in order to overcome things, you have to get out of your personal rut and have the courage to change.
Or as my very wise brother in law says, "If you want to change, then you have to change." In other words, you have put in the effort; it can't be done for you.
In order to get better, you will of course need to stop "self-medicating" as that makes it all much worse, you need to take the initiative of making mental health appointments and taking responsibility for you, and stop assuming like I did that everyone else has it easier than you do.
Even for you to think "oh, will people finally be sorrier for me if I do kill myself" is twisted thinking, to be honest, and certainly not how to go about having people finally feel sorry for you.
It's up to you if you want to get better.
Call someone Monday to get an appointment. Or keep feeling sorry for yourself and do nothing and continue to feel miserable.
It's up to you.
If you are already being treated and you are self-medicating, does your doctor know you're doing this?
