Feeling heavy, bloated in tired in eating disorder recovery?

I'm currently recovering from bulimia. I've not purged (made myself sick) in two months. I got my period a few days ago so I am happy. I feel very heavy, bloated, tired and having very bad headaches.

I've drank a lot more fizzy drinks (soda) and alcohol more than normal so maybe another reason. I didn't celebrate Christmas or New Year so it is not that. I'm also not eating a lot and feeling externally full and bloated when I do. Any ideas please?
