Skeezyks is wise.
Please do try to find social outlets for you and your child, check in your area for mom and toddler groups (the Y often has good programs and scholarships if you don't have the money for a membership), the feelings you are having and the situation you are in is intensified by your isolation. If you can't do it for you do it for your child. (also there are places that have activities (crafts/other) for parent and child). Do you, husband and child do things together just for fun?
I am so sorry for all you have been through, it must be difficult to manage each day. Hang in there & welcome to PC. (((((((((((((((hug)))))))))))))))))))))
