I'd talk to a therapist if I were you. A therapy will help you in understanding yourself better and it will teach you how to control your emotions. When you can control yourself then you will have a clearer insight to any relationships that you are in right now. What needs to be fixed in those relationships, should you stay or not, etc. If your depression is getting worse lately, maybe it is time to get some meds adjustment? Could be the meds you are on right now are not the right ones for you or you need a different dosage.
