Bf with depression he’s getting therapy now

Audrey

So my bf and best friend who has stuck by me through everything even before we were dating is starting to get therapy after breaking down at school. I really do love and care about him so much but his mental health has definitely put a strain on my health I’ve started to become really nervous and crying for no reason and I don’t want to leave him I want to stay by his side but I’ve to talked to my friends (many of them being mutual friends between us) and have told me that I have to look after myself with some saying that we should take a break till we’re both back to normal but I don’t want to leave him at his lowest point (his depression has led to arguments to were he has said some hurtful things and I think that’s contributing to my emotional falls) but anyways what should I do ladies
