This is my first ever reddit post. I've had a difficult past few weeks regarding my physical and mental health, ended up in hospital with a chest infection and while I was there they were doing some mental health evaluations. In an appointment with a hospital psychiatrist (in an outpatient program), after discussing a lot of my feelings he's wanting to diagnose me with Borderline Personality Disorder. In the past I've been diagnosed with anxiety, an eating disorder, major depressive disorder and manic psychotic depression, the latter of which he thinks is a misdiagnosis of BPD. 

It makes so much sense to me and answers so many questions - why I'm constantly worried everyone in my life is mad at me, everyone wants to leave me or doesn't really care, why I have such rapid mood swings day to day, this underlying emptiness, why I dissociate and never feel solid in myself, why I do things or think about doing things I know are harmful. 

But at the same time I'm really scared. I'm scared of what this means for my future and for my present, my relationships. I've started seeing a girl but I keep losing interest then getting super invested and really into her.  The other night we had sex for the first time, I left her place and now I just don't want to talk to her. I broke things off for a week (did a lot of impulsive stuff during) then suddenly I really liked her again and got back together. I don't want to hurt her, she's so lovely but I feel so lost with what to do. 

If anyone has any advice for the new diagnosis, this overwhelm, what to do about the girl I'm seeing and how to talk to people in my life about this I would really appreciate it. I've felt like I'm crazy and alone for so long - hopefully this diagnosis might help me feel more seen.
