Need advice. Very depressed

My partner is friends with people who have treated me poorly, said very bad things about me. At first she was mad at them for it. Now, she hangs out with them. It hurts me. I feel like it's a betrayal. What makes it worse is that she does not want to me to reconcile with them. She wants them to be friends with her only. Also, two days ago she started to tell me something and stopped. I asked her to please tell me and after hours of fighting and arguing she told me. It was nothing significant. I am extremely depressed. I'm going to the doctor in hopes of changing medications. I'm at a point right now that I don't feel like I have a purpose in life. That I'm a horrible person. That I wish I weren't alive. Not because of this. Ive been at a serious low for quite some time now. So, this is all on top of a world that feels like it's caving in on me. I don't feel like she cares about my feelings anymore. We used to be best friends. We were the happiest couple I know. Things just aren't the same anymore. Am I overreacting? Should I be hurt? Should she be hanging out with people who despise me?

Thanks Susie. You ate completely right! I am working in my codependent lifestyle. So, once I tackle that I will probably be so much happier. I've decided I am going to focus on myself right now and put myself first. Thanks again.

Ladeda, I am so happy to see that you listened to Susie and are starting to work on yourself. Please if you ever feel that low again be sure to let someone else know and I am glad you are going to get your medicine changed. You sound like a kind, intelligent person. You can get through this and come out the end even better than ever. Good luck and god's speed, Suzanne
