In need of a boost.

Hi, my name is Alyssa. My friend told me about this site and how helpful it has been to her, and convinced me to give it a try. I could certainly use the help. A little about me; I've been struggling with weight gain since I was 8 years old, and have continued to gain weight for most of my life. I stopped gaining about 2 or 3 years ago and have maintained a fairly constant weight ever since, but I also haven't lost any. I want to be healthy, and I want to be fit. There's so much that I want to do, but can't. Like running, hiking, jumping out of airplanes, amusement parks (i exceed most weight limits), etc. I feel like an adventurous person stuck in a 290 lb girls body. I have receieved some bitter motivation recently to lose weight, and have been working out 30 minutes a day, taking my dog out for walks every morning, eating healthy foods, balanced meals, trying to sleep proper hours, cutting back on portions, etc. However, I'm beginning to feel a slip in motivation. I'm feeling more and more like I have to trudge my feet through quick sand. I am looking forward to using this site, and hopefully it can give me the little push I need. So far, I'm liking what I see! Any and all advice is appreciated, and always looking for friends.
