I don't want to give you empty advice or words of encouragement, i just want to say that you're not a fuckup, you're just a person thats been through a lot up there and need to heal somehow. You're not alone in this feelings, i understand very well what you said. Different lives, different moments, but shared feelings of dispair. Go through the day somehow, and some better days will come up where you can do something else. My wishes with you
