...love. It'll be 2.5 years in December, and we have just as many silly, goofy times (along with as much romantic spark) as we did when we first met. I'm so happy to have someone who I love who loves me back, understands me, and believes in me.
...my job. It may be boring, it may not pay very well, and I may be hunting for another one, but it serves its purpose and I am happy it's there. I've seen some pretty desperate, destitute times and I'm glad that I can at least survive now.
...my family. Even if we disagree on some things, I'm still close to them and their hearts are in the right places. I love them very much.
...my friends. I've been blessed to meet some amazing people.
...my fans. I feel strange typing that out because honestly, I do not think I'm a big deal, but almost every day, someone finds me on here from one of my TV appearances and writes me. I'm thankful for the supporters... and I don't give a shit about the naysayers...
...my health.
...my body. I gained 50 pounds about a year and a half ago, which was very hard on me both mentally and physically. I lost 40 of those 50 pounds and now wear the same size, in addition to having much better muscletone. I'm thankful that I lost those 40 pounds quickly and easily (4-5 months) and did not face too many obstacles. More importantly, though, I am thankful that for the FIRST time in my ENTIRE life, I've found peace with my body. I'm slim and fit without having an eating disorder of any sort, which is a first for me. I no longer hate my body, as I did for so many years no matter what size I was.
...my creativity. I hope one day I can actually use it.
...my intelligence. Sure, stupid people may be happier because they're too dense to realize their life sucks, but I'd honestly gain 50 pounds before losing 50 IQ points (which, by the way, would put me in average range) 
...my friendly disposition. Now, some people might think that's a silly thing to be thankful for, but I've heard that some people really have to try hard just to be kind to strangers.
I'm sure there's more, but those are the immediate things I'm thankful for.
