Drop 40! Need some accountability help!

So I had my 3'd child 6 months ago. I weigh more now then I did at 9 months pregnant with my first! I NEED to lose this last 40 lbs. I have exceptionally low self esteem, depression, anxietyx1000 and so on. Some days motivation is so hard. I feel like if I can look in the mirror and like what I see then maybe my emotional well being will be more intact (and yes I'm working hard through all these issues as well!) Anyone going through anything similar?
