I'll lay this out like Triggey:

1. Honestly get over it. If you cant see a brownie and not eat it you need to work that shit out. Think of it this way, what would make me feel better, eating a brownie, or not being fat?

2. There is no reason you shouldnt be doing cardio. Start out slow, and work your way up, I would go 3 times a week, around 30-40mins per session at max.

3. I wouldnt do cruches at all right now. you could do them till you pass out they wont make you any thinner. If you absolutely need to do them, throw them in with your wieght training maybe twice a week, but dont sweat them.

4. What Triggey said.

I would also add that your diet is gonna make or break you here. I'd read everything you can on this site about dieting and fatloss. there is a lot here, and you will find something to get you to your goals. All you need to do is man up and you will be fine.
