It's so hard to avoid it when it's your only source of happiness in an otherwise depressing life
Like it feels so so good. It does feel really bad too and it takes you to such dark places and makes you do things that you wouldn't do if you were sane... But when things go well it's like you're on a perpetual dream; all your problems suddenly don't seem so important and you don't worry about the future that much and you stop crying every night until you fall asleep because you feel like you actually have a purpose now, because there's something that gives you hope. You feel human again, there is SOMETHING to look forward to, even if it completely messed you up, even if you sacrificed youself, your career and your friends for that person.
It's hard to explain why one would be willing to ruin their whole life for someone else but it just feels that good, it's addicting specially when your life is otherwise horrible.
I don't know what to do because it's coming back. I have a stable life now and I feel the urge and I don't know what to do to avoid it. Because pursuing it will make me deteriorate, mind and body, and destroy everything I managed to achieve. I'm scared and I don't know what to do
