Bailey do not be afraid to go outside because other people laugh or give strange looks.I was in like the same sitch I lost 320 lbs in 2 years. People are mean they used to call me "the Big Bluebrry" and scream every time I walked down the hall so when I started to work out I would try to prove them wrong and that is what kept me going. I suggest you get a Tread Mill and pick so many miles you would like to run a week. STart with like 15 the first week and try to build up each week. Now I weigh 135 lbs 5'5> well that is my sucess story I hope to see yours soon Thank You and I wish you luck.
