Am I sick or just feel weird.?

Moriah
The last couple days have been weird I just sometimes aren't felt like me. I've been more tired. I'll have slight cramps (not on my period) or belly pain. Breast hurt and if I rub my nipple because it itches then it feels like I was just being sexually touched (because it felt sensitive?) I've had to (sometimes) pee a lot (I pee a lot anyway though because I don't like to hold it/I drink plenty of water). I'm always picky when it comes to food but lately I don't want anything and I'll just have to eat because I'm hungry. I get sick to my stomach (especially around cleaning products) and feel like I am about to shake (I'm anemic, and hypoglycemic a vegetarian also so I have to watch my foods anyway) I've been in-taking my nutrients I feel like I should so I don't think feeling bad is causes by lack of nutrients if your worried because the fact I'm a vegetarian.. Suggestions of what is going on?
