Jordan gave you some good suggestions.The first thing is to get the drugs out of your system,and NA meetings can definitely help you do that.Use caution at the meetings, and stick with the women who are working a good program.Resist the urge to hook up with guys at the meetings.It can seem lonesome at times,but you really need time to work on yourself.
Counseling can probably help with the other issues.I can tell you that it is possible to get clean/sober and deal with depression and anxiety.It's been a problem for me as well.But it is very treatable.Once you get a handle on the depression,and start working the NA steps,I think you will find it much easier to stay out of unhealthy relationships.Start now,by believing that you are worth it.You deserve a good life,and you can do this.Keep posting
