Support is very helpful, it can give you the motivation to succeed.
However, when you rely on someone else for that support it is easy to lose the motivation when the support is no longer there.
I like to surround my self with people who are fun and truly nice people. no matter what size they are.
I like eating healthy so I don't let their food choices bother me. Saying no thanks to the junk is fairly easy when I know it will just make me feel bloated and tired.
If you want to be healthy and fit, no one can stop you because it is your decision to just do it or to use an excuse to just give up.
