I have been with my boyfriend for a year now. We started seeing each other when I had first been diagnosed with BPD, so he has seen me at my worst many, many times. At the moment my mind is in a very dark place, and I feel like he is my sole source of happiness right now. When I am upset I almost always turn to him for comfort. He is the only person that can calm me down; being in his arms makes me feel like nothing in the world could possibly hurt me. I know he can't always be there, and that it would be so emotionally exhausting for him to have to constantly deal with my shit, but I just can't seem to stop relying on him to help 'make things better' when I'm down.

I begun to realise that I am on a very self-destructive path when I thought about what would happen if he broke up with me. If he ended things I feel like I would not be able to face the world anymore. He is my rock, and at the moment he feels like the only person in my life that I care strongly about. I have come to the realisation that I really don't have many other friends, so I wouldn't have anyone to console me if things ended. 

It is quite frightening to think about how reliant I am on him. I'm not trying to magnify the negatives by focusing on what would happen if he did break up with me, I guess I just want to learn to not be so reliant on him in case one day he isn't in my life anymore. Because while I don't want to think about losing him, I want to be able to know that I would be a strong enough person to be able to carry on without him if things did go sour. And I also want to learn to not be so reliant on him so that I am not constantly burdening him with what is weighing down. 

So i guess my question is, how did you learn to not be so dependent on someone?
