You are dealing with a number of recent losses which understandably have made you upset. On top of that, you have noted possible symptoms of depression.
I don’t have enough information to know if you made the right decision regarding your girlfriend. You said that staying with her would’ve led to severe depression but did not say why. If you are correct, then it would seem that breaking up was the right decision.
She is also experiencing her own psychological difficulties. Neither of you sound healthy enough to maintain a flourishing relationship, at this time. After you both are more stable, maybe then consider reestablishing the relationship.
You should consider counseling. Depression and relationship problems are two of the most common reasons people enter counseling. Counseling can provide you with guidance about your relationship and teach you how to manage your possible depression symptoms.
Another option is a grief/bereavement support group. Many people benefit from talking about their losses. Sharing your loss often facilitates the healing process.
Once you are feeling more stable, you will be in a better position to make decisions about your future and with whom you want to spend it. Please take care.
