Ffs, this whole thread is just full of toxic positivity as far as I'm concerned.
The reality of it is that the reason why it hurts is you're essentially being kept alive artificially. As at any other time period you'd have just starved to death or died to freezing a winter or two later, putting an end to the misery.
Can you still have fun moments and learn to live your life as a glorified leech? Sure, a lot of people do so, and our society has decided that's for the best.
And in case you or someone else has an issue with the term leech here I'm going to be extra clear: you need to face reality to get over this pain. Accept what you have been forced to become. Then you can make an effort to life with your lot in life, and potentially find acceptance to the cards you've been dealt.
Probably wasn't your fault and almost certainly unfair, but that's just how life is
