I've been getting my life together, my finances, figuring my shit out. I'm trying to be positive and make good changes, stop eating food that makes me sick all the time. Just simple things but I've made some big changes. I almost feel high off of it, but now my scissors beckon me once again and I do not understand why. Every time things are good in my life I find some way to sabotage myself it's so disturbing. Is this a bipolar thing? I feel like I'm living in a fucking horror movie
I don't really know you or your situation but this kind of thing can be caused by all sorts of internal and external circumstances.
Sometimes people self sabotage because of low self esteem. They feel like they don't deserve to have nice things so they hurt themselves in order to feel less guilty.
This kind of response can also be due to fear. If a person is used to having nice things abruptly taken away from them by others, it can be easier just to self sabotage. That way, they feel there's no chance that things will spiral out of their control.
Other times it's just a matter of familiarity. Coping with change, even the good healthy kind, can be very difficult for a lot of people. Because of this, when making changes for the better someone might feel the desire to return to older, self destructing habits. Because that's what's familiar.
I'm not sure if any of these reasons resonate with you (because I don't personally know you) but I hope this was helpful and I wish you luck on getting to the root of the issue!
