It really will help you get stronger the more you learn about addiction and co-dependency.
Don't feel bad about being co-dependent. Addiction sucks you in. We do what any compassionate person would do to help another person. Only when you help an addict
it usually just enables them to continue using comfortably. So we keep helping, they keep using/abusing us... the cycle repeats. Kinda like a roller coaster ride.
Concentrate on going to university and getting your thoughts healthy. You deserve a life full of serenity, peace and joy! Consider this a learning experience. Keep posting!
