I have started living with my friend who has BPD and I feel like she is relying on me too much for small things in a way that is starting to affect my mental health.

It's getting to a point where when I say no to her she has big meltdowns and spends hours in her room crying loudly. She won't do anything on her own but I don't think me doing everything for her is helping her I think it's making her worse and I'm scared for her. 

She is soon to be getting help for her BPD. I just need some advice with setting some boundaries on what is my time and when she needs to do things herself.

I need to learn on how to say no to her and put myself first without really upsetting her.

I love spending time with her but I just want to try and make that time more positive for her and me.

Thanks in advance.
