In need of a support group

So im starting my challenge to myself to loose 100 lbs. I promised myself that I would have it off by 30 but here I am 30 yrs old now. I don't feel like I can ask friends for support cause they don't have that problem. Its just really gotten to be pretty bad lately and Ive become very depressed and antisocial. I would love to get a group of us to encourage and support others out there.
