New to this and need help

I am a young 24 year old financially independent woman but I fear that I might be codependent when it comes to emotions. I always go for relationships with people who need me but in the end I really need them to help me remain sane. I have friends who depend on me for everything and I help them because it gives me a sense of importance. I stay in relationships long after they have become painful only because I need the relationship to stay happy even when I'm really miserable. Right now I have to end a relationship and I don't know how to do it because I fear being alone. In my current relationship I have spent a large sum of money on my partner of less than a year. Things are going wrong but I still try to keep the relationship going. I just need some help in coping with this and becoming completely independent. Tweet
