Honestly I dont really cope, I just suffer. Even with suicidal ideations I just wait till it passes.
It's better to see life as a video game and relationships as transactional at this point, it doesn't serve you (me) to expect genuine relationships or love. Just focus on accumulating money like a videogame (without killing yourself over a job that you hate) and distracting yourself with fun things. Drugs that have some therapeutic aspects like psychedelics, THC, and MDMA are actually not that bad either in moderation. I don't have any right now but if I had access to drugs again I would do MDMA maybe like 1-3 times a year, you really don't need a lot. Or do a shroom trip like every other month. MDMA actually reduced my suicidal desires though nothing has majorly changed in my life from the molly alone. I barely get suicidal ideation anymore except a light desire once in a while now and it's been over a year since my last dose.
Even my own family members and relatives wanted me dead and demanded me to write a will to put them as inheritors in the case that I die once they realized I had some money that they think I didn't earn and deserve (because I am just a lowly soldier and not a college educated white collar professional like them yet I had more money than their kids). I was only in my 20s too so there was no reason to expect me to die anytime soon.
I haven't had any friends for 5 years now, and I've been eating alone (usually in front of a computer) for 15 years now. I got used to it. I come from a really fucked up family and even my "friends" were making me the butt of their jokes so I left them.
Get NEETbux if you can. Just work with the therapist and bullshit and keep bullshitting until you have enough documentation saying your disability is too severe for you to work. Just fucking play the game. Just do it.
Get money however you can without high risk of jail time. I had to join the military myself that pretty much gave me a huge advantage in life, though I was humiliated and looked down on for it. I never went into the military for the benefits nor even knew how much it will benefit me, but I am glad it did. Not everyone qualifies for the military. Try something else then. Do whatever you have to do. Money solves a lot, trust me. It might not fix the incel life, but it makes everything else more bearable. Get the money first before you decide whether it's worth living or not. You can always kill yourself later. I would say it's still worth staying alive and distracting yourself as long as you're still able bodied and in shape, and not to kill yourself until like age 45 because that's when shit goes downhill physically and your life options have narrowed by that point for most people who don't have basic social skills or looks or leverage.
