NEED MOTIVATION

I am 5'2" and pre pregnancy I weighed 159. I had just lost like 40 lbs. AHHHH and I gave birth at 241. Current weight is 174 and I have a long way to go for a goal weight of 120. I am new to my fitness pal so please feel free to add me. I need all the motivation and advise I can get. I saw my Dad pass away a few years back and gained 80 pounds. I was always small through high school and was a cheerleader. now I run from people I went to school with and avoid crowded places. I want to be able to look in the mirror and recognize the reflection. I have not felt confident in myself in over 7 years. Please help!
