Yes, I had that about 10 years ago or so. I dealt with it by fighting it. Somehow the label, even the words themselves just pissed me off one day. There was a long time when I revelled in it. But gradually I got tired of living like that and just clawed my way up and out. With the help of meds, therapy, gin and a lot of time. And ending a toxic relationship with a married woman with 3 kids (I'm female). I moved, retrained, got a new career, basically reinvented myself. It took years and a lot of pain and misery and whatever else you can think of. It was not a fun experience but the end result was worth it. The journey was crap. I hope your path is smoother, shorter and a lot more interspersed with joy.
