It's hard at first trust me. I really know what you're saying because only about a year ago I was 330lbs when I first joined the gym. Seeing myself in the mirror every time was very disheartening and the gym owner even told me later that some people at the gym would tell him that I won't last long (though I did and dropped to 172lbs, but I digress). But it gets better. Eventually you start liking the weightlifting, the walking, the jumping jacks and what not. Then you start making small goals, you start taking more pictures because you start liking the way your body is changing. You gain strength, you can run up the stairs. In the end, when everyone praises you for it, it's a very great feeling, although I'd say the true happiness comes from not hating the person in the mirror and I got to that point quite late. I don't shy away from pictures anymore, I'm more confident around my friends, I feel better when shopping for clothes because I know I won't have to go to another store if this one doesn't have the size I need. It's the little things in life, you know. After having lived at least 99% of my life being obese, this is a whole new experience. It's like I'm reborn and even though the challenges remain, I feel confident that I can do something about them.

I'll still encourage you to go to the gym. You'll be doing it for yourself and no one else. It doesn't matter what everyone else looks like. Everyone at the gym is struggling in some way. Skinny guys want to bulk but keep failing, girls struggle with strength training, old people can't walk as much. Take it one day at a time. Small consistent efforts make a huge change in the end.
