A few days ago I posted a thread here, about how my boyfriend had said he was going to play video games after I'd confessed I was having suicidal thoughts, due to him not being able to handle me during bad BPD episodes. 

After getting some great advice (thanks everyone), I had a good talk with him, and we've basically agreed that I can no longer vent to him when I'm feeling negative emotions due to the fact that he has problems of his own and is unable to handle mine. 

I'm fairly okay with this in theory - he has depression and anxiety and he really shouldn't have to deal with me during my worst times when he already has pretty severe mental health issues. Still, I'm having a bit of a rough time. 

See, back in the early days of our relationship I was still closed off from pretty much everyone, pretending everything was okay while I was hurting so badly on the inside, and it was because I finally opened up to him and vented about my problems that I was able to recognise that I did have issues and that I needed therapy (which I'm currently doing). 
He was basically my most trusted person, the one person in the world I could talk to absolutely anything about, who was there when I was at my lowest and who always helped me feel better. 

But now, I don't have any of that. I can no longer talk to him about whether I had a bad day or if I'm feeling sad or worthless or angry or self harming again because he's unable to handle it. 

Although I'm really trying not to, I feel abandoned and hurt. I understand why he struggles to help but it still really hurts not having anyone there to rely on when I'm feeling low, especially counting the number of times I've helped him through panic attacks and depressive episodes. 
I've gone from feeling like I can talk about anything with him to not having someone to talk to even when I'm just having a bad day and want some words of encouragement. 

Who else can I talk to? I don't have close friends who would be willing to listen to me when I'm like this, and family is out of the question. I have a therapist but it takes forever for me to open up to people and I don't feel like I can trust her. And how can I train myself to not rely on him to make me feel better? I just feel really alone at the moment ...

**TL;DR:** Boyfriend has confessed he can't handle me venting to him when I'm feeling negative emotions, hence I now don't have anyone to talk to when I'm feeling sad, alone etc.. Who can I talk to/what can I do?
