<human>: I will try to keep this as brief as possible.  
My boyfriend and I were together for just shy of two years, after knowing each other for a long time.  We were very much in love; we were best friends, we lived together, had strong relationships with each other's friends and families, and had even talked about marriage.

After making a big cross country move back home, he started to feel extremely self-conscious about his career and direction in life.  It continued to spiral downward over 6 months to the point where he barely wanted to go out, and his infrequent work situation caused him to continually be stressed about money.  With the stress of the holidays on top, we were fighting.  I thought it was a rough patch.  He came over a few days after Christmas, broke down, and broke up with me, referencing his depression and needing to make a change, but not knowing where to start.  We have acknowledged that we love each other, and over the past few weeks have talked on and off, but he is still unsure of what he wants and I had to cut off contact for my own well-being.

I struggled with depression and self-harm issues a lot when I was younger.  After ending other (unhealthy) relationships, I relied on drugs, alcohol, and hookups as a means of emotional validation and distraction.  I don't want to go back to old habits; plus, this relationship meant far too much to me to be emotionally "swept under the rug," so to speak, and I want the healing process to be healthy.  I just don't know where to start.  I am devastated.  Any thoughts are appreciated.
