Weight Issues

I'm watching Discovery Health about obesity and the home in Andover and I feel so sorry for them because of the work and willpower it will take to get healthy and where they want to be.
2 years ago when I got married to Shawn, I weighed 104 and felt beautiful and small and was able to wear the cutest clothes-so much variety and style.  I didn't have any problems wearing anything and my wedding dress was beautiful and validated how I want to look.  I do realize how vain this sounds.  I was doing ok but started gaining weight this past summer. I quit smoking in May when I had a bout of asthma.  I apparently was give a too high dose of steroids.  I've also been on Seroquel XR for quite some time and that can lead to weight gain.  So from say May till October I gained almost 50 pounds. 
I definitely feel different-I've never had to be so limited on clothing and was really shocked at the choices in comparison to "skinny" clothes-especially since my weight now is more the norm than before.  Plus my body feels like it's not all mine and I certainly feel like someone else when I look in the mirror-I have no problem
with weight, it's just not me.
So there are tons of options and ideas to lose weight-however I don't exactly have the willpower or what I like to call say-no-ability, especially if I'm having a bad day or feeling like I'm never gonna get back where I want to be. 
I walk on the treadmill, till I hurt my foot and have been doing a lot of crunches and at the very least trying to ease up on my amount of food-one good thing is that in the winter I'm not usually as hungry.  The hundred calorie snack packs or slimfast do not work for me cuz I can just have another, lol-defeating the whole purpose.
What I think would help is one of the food delivery weight loss places-problem with those is the cost-it's impossible for someone like me to afford.  But I also know with that limitation to just their food would make a huge difference.
Surgery of course would help-tummy tuck, lipo, whatever-but there is the cost and also I do not like going through surgery ever never ever.
So what I guess I'll be doing is continuing to eat less-say no an extra couple times a day and try to stay active-hard to do with my hurt footsie and just make sure I don't deprive myself because that usually leads to binge eating and no, I don't throw up after.  I'll get my body back, just gonna take more work I guess now that I'm getting older. 
I still have all my real Jennie clothes and will be wearing them again.
Oh-I did get some great bigger boobs with this weight which when I'm dressed helps actually make me look a little smaller, but the weight is still there and I know it so it's not ok by me, but I do hope that God will let me keep the boobs as a bonus for my hard work. ")
