I was talking to my best friend a little bit again, the one that said they wanted a bit of space from me because I was being a little overwhelming, because they said I could still dm them a little bit. I started talking to them again yesterday after completely leaving them alone for 2 days. I felt miserable until I talked to them. Again, the BPD kicked in and gave me a sense of euphoria. I took that too far and started talking to them a lot more again. They told me they needed more space, I wasn't giving them enough. They said it would be best if we didn't interact at all for a while because I wasn't giving them enough space. I fucked up again. The 2 days without them was miserable. All I did was sob. The whole time. I can't live without them. I know this is my fault, but I don't know what I can do. I feel like I can't live without them at all. It hasn't even been 5 minutes since they told me not to talk to them at all but I'm already sobbing. I can't even interact with them on a common discord server we have with a couple of mutual friends because they said they wouldn't be active for a while. I'm so done. I'm not mad at them, it's not their fault. It's my fault. But I really can't stand being like this. 

And obviously this happened right after therapy ended too, I can't even talk to anyone about it. Could anyone please give me some advice? I hate that I'm so dependant on my FP. I really can't do anything. I'm pathetic and useless.
