My sister had a small battle with depression (it started as untreated post partum) and was on medication for a short period in time. My mom and I have been on medication for depression and anxiety over half of our lives, my dad started anti-depressants last winter.

You need to see a mental health professional. Even if this is physically related, a mental health professional can help you deal with the anxiety aspect. It is hard, no doubt about it. Luckily, after being diagnosed ADD and starting those medications, my anxiety has lessened to the point that I am dropping my Paxil dose again. I have been where you are, so if I can help, please let me know.
