Scared to get pregnant due to my anxiety

I am 31 and at that age where all of my girlfriends are married and either have a child or are pregnant. I used to desperately want children before my anxiety and panic attacks started back in my early 20's. I am a caregiver by nature and love people naturally, but my anxiety attacks are so dibilitating that I have become agoraphobic and extremely depressed where I can't take care of myself let alone anyone else. I  currently am mentally healthy, but if you have anxiety you know there are highs and lows. This has been very hard for me to digest due to deep down wanting a child but fearful that I wouldnt be a healthy parent and able to take care of the child like he or she deserves. My husband is wonderful and would be a phenomenal father, but is that good enough for a kid, have one solid parent and one half reliable crazy lady for a mom?  Has anyone dealt with this and had kids?  Not just generalized anxiety, I'm talking mental breakdown anxiety.  I would really appreciate to hear your thoughts. Thank you!
