What’s Wrong with Me?

I’m nauseous every one in a while now but lately I have been constantly throwing up right after I eat. I can’t seem to keep food down. This has never happened before plus I’m constantly “bloating” but my stomach sticks out a little further every month. I’m tired all the time. I’m having insomnia. I can’t eat chocolate, or pickles which is weird because I could eat pickles all the time with sandwiches but now I can’t stand the taste of them. Instead I am craving onions and cheese which is totally not normal for me. I’m going crazy because this is not only happening during my period but it’s happening all the time. I wish I knew what was going on. Can anyone help me understand this if you have had anything like this happen to you?
