Welcome to Sober Recovery. You are at the right place. There are a lot of great people here who have been in similar situations as yours. The alcoholic in my life is my father, and my mother is a drug addict. I live with my RABF (he has been clean from drugs for over 2 years).
I would suggest that you read the book Codependent No More. I have read through it at least 5 times. I was amazed how I saw myself in the book. I learned a lot from it.
Congrats on being in school. I had some battles to complete college, too. I was dealing with my personal issues, plus I also had boyfriend issues. My financial situation was also really bad, but I made it through!
