Help!!

I'm a mom of two, 1.5 & 2.5 years old. Its only been one month since I've stopped breastfeeding and in that month I've gained almost 10 pounds. I feel as though I'm falling into a deep depression / hole that is only getting deeper. I can't seem to loose this weight. The more weight I gain that more I think I will never loose this weight. I'm becoming very uncomfortable in my own skin and don't want to leave my house. I need help. I need accountability. I don't know what to do and I don't want to wait until rock bottom until I confess that I NEED HELP!!
