Thanks for the responses and "welcome backs," ladies. Sorry it took me so long to write back!
To answer a couple questions/statements:
nelie, I braved the scale after I read your post the other day. 280 pounds

I guess I'm glad to know, but it just makes it seem so
real.
Eliana, no I haven't really started any diet yet. Basically, I don't know what to eat at this point. I get grossed out by meat and would like to be a vegetarian, but I don't like vegetables (big surprise, huh?) so I basically end up eating junk. The fact that a major hobby of mine is cake decorating doesn't help either. I tried a couple months back to just jump into salads and, well, needless to say it didn't happen!
About hiring a personal trainer: the thought scares the heck out me. Not for the reasons it should, but because of the other gym members. I've been a regular and heard the "I can't wait until February when the gym is empty again" comments. I know it's silly, but I'm so paranoid about what people think. I don't think living in San Diego has been good for my self esteem! At any rate, I've been avoiding the gym like the plague since my weight went back up. We have a treadmill, some free weights, videos, and all that good stuff. I'm hoping to at least get started at home until I get the nerve up to step foot in the gym again.
I'm actually starting to look forward to working out again, gym or no gym. I saw the link that nelie posted (I think it was her!) to the stumptuous "no fat chicks" article and I think I'm going to start with that. I think the only modification I'll make so I can do it at home is the lat pulldown.
Anyway, thanks for the support ladies. That's why I missed this place
