well.. working out is not the only way to loss weight.. i will suggest you to make friends who daily visit park for walk.. once you like their fellowship you can stay do fun things with them.. dancing is a best way to reduce weight... find a partner for that.. once you find a good friend.. convince him for couple dance.. it will occupy you mind so it will help u get out of depression.. and and it will reduce your weight.. have fun...
I don't really have many friends either (long story, multiple reasons) but even an online buddy can be a help; you could have friendly competitions to see who took the most steps in a week (pedometers are cheap and sooo easy to use, just keep track of daily totals on the exercise tracker here) or something like that. Even on my own, I find music to be a great support. You can totally just get lost in your favorite tracks when they're turned up loud, and music can help with depression too! I hope you find someway to start feeling better.
Thank you very much for your comment. I am suffering from sever depression and it is very hard for me to get out being that I have no friends to help. I guess my immediate problem is to find friend support.
I agree with cutensweet, You can do any activity you like it may be swimming, biking, walking, running, jumping, dancing, etc.
