Listen. To anyone reading this thread, and similar threads in the past and future. The discussion may be amusing to you, or perplexing, or frustrating. It may even be pulling you down.
If you feel like you're going to harm yourself, call 911 right away, or whatever your local emergency number is.
If you are having issues, get help. Ignore all this talk. Maybe you're depressed. Maybe you just think you're an asshole, because it's hard for people to be around you and hard for you to be around people. That's not natural, we're social animals. It's not "wrong," it's a symptom.
Don't second guess yourself, don't overthink it, don't try to tough your way through, get help right away. If you have access to a doctor that's probably the easiest way to start. The doctor may treat you himself, or he may recommend some other treatment. The point of the initial visit is evaluation. They're trained to do this.
If you don't have easy access to a doctor or other professional, don't give up. If you're working then your employer may have an Employee Assistance Program. They're free, and you can get a few initial visits with an appropriate professional. EAP usually offers lots of unrelated services, including legal advice, so don't hesitate to ask HR or whoever for the brochure or information, they won't know why you want it.
You may have to go through your county's assistance resources, and that's potentially frustrating, but do it and be persistent. Get a friend or relative to help you navigate.
Me: My car won't start. I need to get rid of it.
Mechanic: Actually all we need to do is replace this solenoid. You should probably change the oil a little more often too. The car is actually pretty good.
Me: Oh, good. I'm glad I asked a professional. I kind of like this car, and I'd like to keep it.
