Hey, TypeN, I'm very sorry to hear all the stuff you are going through.
I hope you can manage and I hope you find courage to go through all of it.
I come from a dysfunctional family as well and I know how powerless you must be feeling right now, and how tiring it is to deal with all of it.
Also the uncertainty of the future is killing. I have been very anxious about my situation lately. I'm looking for a house in a very complicated place to do that, and it's a very similar experience as the one you explained with the hiring process. These days I have achieved a point where I just don't longer give a fuck about it. Is not like I don't care, I just try my best, I put my effort on it and then I don't longer give a goddamn fuck about what happens next. I'm doing my best and trying very hard, I just don't want to become crazy about the things I cannot control (the decision of the landlords, other people competing with me, the answers I get, etc...)
I hope you find something that helps you to don't loose hope and to keep trying, even if it's difficult I think it's worth it to just keep trying until something's comes out.
I also hope you take care of yourself, even if it feels shitty on the moment. You know. Eating healthy, don't isolating yourself, trying to be social and do rewarding stuff, sleeping properly and not going back to addictive behaviours to deal with emotions. I know it just doesn't feel right on the moment, but that's the way to go, as you probably know (I know a thing or two about depression, hehe
Have you explored a way of expressing your emotions? Any kind of art(maybe drawing), talking with a relative, a friend or a professional, meditating...
I mean, if we are to best this adiction we will have to figure out some way of dealing with emotions in a healthy way.
I know is difficult and I'm still figuring it out.
This is very personal, but sometimes I feel music can be a great company. Sometimes you find a song that gives you the feeling that is talking directly to you. I use it a lot as a support, it can be cathartic and reassuring. I leave behind a couple of songs I'm listening a lot lately.
