<human>: I'm going to be so completely brutally honest in this post, more than I've ever been with anyone in my life, much less on the internet. I was looking at another post here on reddit, an AMA from a guy who lost over 250 pounds. It made me realize something. I need help. I am so depressed about my life. I'm severely depressed about the way I look, about the way I feel, and about the way I am in this world. I want to live life to the fullest. To be the best that I can be, and I'm sick of being so embarrassed, so humiliated about the way I look that I've closed myself off to nearly everything and everyone in my life. But my fear is that I can't do it alone. I've tried before, and failed miserably because I wasn't strong enough to see it through. It's so easy to run back to old, familiar, comfortable habits. 

I'm 26 years old, and I currently weigh 450 pounds. I'm looking for anyone who may have some advice, some encouragement, suggestions. Anything to help me see this through. Any suggestions about foods to eat, things to do or try. Anything to break free of what's causing me to be so unhappy with myself and my life. I'm so tired of it all. I just want it to change. As much as I hope that there someday will be a magic switch I can flip that will make my health issues go away, I know that it isn't coming.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Hate the way I look, extremely unhealthy. I want to change but I don't think I can do it alone.
