Good day Lynn,
I am so sorry that you are feeling so low, after reading your post and you mentioning that you have 3 children, I hope that you can come through this funk for their sake. I can't offer you any suggestions about medications as I live in Canada, but what I can suggest is to keep posting your feelings on this site and you will always get someone that can offer you some words of support that will hopefully help you through this difficult time.
I was admitted to the hospital 6 or 7 times last year with a suspected bowel obstruction, and each time I got depressed, (which is normal, being in the hospital is awful) but once I was at home for a few days, I snapped out of it. Give yourself some time, and if you are still feeling really low, try and make some calls so that you can talk to a professional to get some help.
Hope some of this might help, try and keep your chin up Lynn, you have people rooting for you.
