21 years old and trying to lose 60lbs

Hey everyone, I'm 21, still in school and a single mom to my son. I gained so much weight during and two years after my pregnancy I started not to recognize myself in the mirror. I would love to have some friends to help encourage me and that I can help on the journey to lose this weight and start a healthy lifestyle that I can show to my son. I'm trying to lose 60lbs by the end of this year, I know it sounds like a giant goal but I have dreams for myself and to achieve them I have to push myself.
