New-ish to MFP, looking for supportive fitness friends

I have been on MFP for over a month, but have only had the app and never knew there was a comminity like this or anything. I just thought it was an app for tracking calories! This may be exactly what i need to stay on track and i would just love some supportive friends to help me stay accountable. I am 19 years old, 5'7", and am at my highest weight of 275lbs. I am terrified of hitting 300lbs and i know i need to make a change now. I am still trying to find the exercise that I love and would love some mew ideas!
