I've recently spoke to a psychiatrist who says I have depression with "displays,/tendencies of Bpd" and I have no idea what to do with this information. I brushed it off at first but have begun to realise my symptoms are not normal depressive symptoms. 

Being alone triggers me to the point I have severe lows and self harm. I am so unjustifiably fearful of my partner leaving me, the smallest change in their tone sends me into a downward spiral of overthinking and doubt. 

I am constantly depressed that I feel like a burden and that everyone is going to leave me because I can't seem to go a month without something upsetting me or just being fucking ok for once. 
 
I have very few friends and have cut so many people from my life over the smallest dispute. I am just so lost and haven't the faintest idea what to do anymore. 

The worst of it is, because I am not officially diagnosed just displays/tendencies, idk if they can offer the support for this kind of feeling/ behaviour. 

I don't know what you guys think about what I've said, it it is indeed as the psychiatrist said or if he is wrong I'm just kind of lost.
