Tick tock

So I’ve struggled with Panic Disorder with Agoraphobia on and off my whole life but after my mom died I lost it. I haven’t been able to go very far places or on a plane and my husband has to do things on his own a lot. Well the other day my husband said if I can’t get it together and be able to go places he wants to find some one else because having a baby is important to him and he doesn’t think I will be a good mother if I can’t travel and go a lot of places. I have wanted a baby for so long and he wears condoms AND pulls out so we won’t get pregnant . I’m devastated because I just turned 33, he’s turning 40 and I feel so much pressure now to “get better” and I just can’t believe he would even think of leaving me for something i can’t change. What do I do?
