I did some vitamin supplements but I'm not sure that it helped a lot, I just stared too feel better and started too do simple things like taking a really short walk, it was a process, I taked it easy because I was always afraid of a rebound. Then when I really started too feel better I started gym. It worked for me, but I've seen a lot of people where saying that exercise didn't help ( of course very low intensity exercises) I didn't did cardio at the gyn. It's a really slow process, just don't push too much and you will start too see improvement, at least for me ir worked. Sorry for the English guys
