Losing weight

I am 21 years old, almost 300 lbs. I've wanted and tried to get to my ideal weight for the longest but everytime I try i fail. I used to be super athletic but no I find myself skipping workouts just because. I wonder if there's someone in the orlando area who would like to go to a gym with me, someone competitive and friendly cauz im little shy loll. I live around Piedmont lake middle school in Orlando and would love to have someone like that to help motivate me as I motivate them.
