<human>: Provide a brief overview of the text.

Right, I've posted here before and I can't help but feel like I'm doing everyones head in. But here's effectively the situation:

I am 20 years old, I lived with my Narcissistic mother till going on a few months ago now. She and my step-dad was emotionally abusive and as a response to that I have anxiety and depression and I struggle with my emotions and thoughts.

My girlfriend at the time helped me a lot through moving out and I'm now living with my father, thing is she has BPD (Borderline Personality Disorder). I broke up with her maybe just going on 14 days ago. and since then I've got back with her maybe three days ago and realized I was manipulated into doing it and cut it short (I felt like a horrible person doing it). 

She is still trying to get me back, but I don't know how to tell her that I don't want a relationship, how I can't cope in that situation but she keeps saying things like "You're pushing me away", "I'm more likely to get more depressed without you". And it's almost like shes making me feel guilty for not feeling anything for her anymore I feel horrible that I don't, right now I feel so confused I really just don't know what to do or say. All I want is time to myself, to be left alone, honestly I can't think straight when it comes to this I feel like I'm being manipulated.
<bot>: Girlfriend with BPD wants me back I feel like she's trying to manipulate me into doing it and guilty about not feeling anything.
