Ok, I din't know if I wanted to post, but I think I need to hear someone else's thoughts on this. Let me start from the beginning. And i'm so sorry it's long...

All summer long was one big anxiety fest. Though things turned out alright, i'd get very nervous before hand if things weren't going as they should have. Finally, the last week of august, it hit: I just had full on anxiety 24/7. Couldn't shake it. But when that saturday came, I seemed alright. But for that whole week, I couldn't eat much. I think I lost about 5 pounds throughout the summer, and I don't like it. I'm thin as it is and now I really want to gain my weight back.
I got a physical the week after (so 2 weeks ago, now). Everything was fine. But the next day I felt pains and I thought it was gallstones. My mom told me not to worry, I figured it was muscles and was fine until it wasn't letting up so I saw my doctor again the following monday.
He said I was fine. My blood results came back from my physical and they were great. No signs of anything. He also said i'm so thin he could feel my gallbladder and it was fine. He said it was muscles, like I had thought.
So the pain actually finally subsided a few days ago. I got my period saturday so it just ended. And I finally told myself that i'm ok, i'll be ok, just don't worry about anything.

Monday night I felt bloated. Tuesday morning the same and I vomited a little but I think that was just because I was nervous. I only threw up the orange juice and water I drank that morning and I felt fine afterwards. I figured it was my period. Then for some reason, last night I couldn't eat my dinner: I felt very full. I went out with my mom for a couple hours and was able to eat icecream when I got back. But today I felt full the entire day. I tried eating some peanuts and 4 chicken wings but that's it. Tummy isn't growling at all.

Now here are my questions:

even before all this happened, the week after my period used to be my pms week, meaning i'd feel bloated and moody instead of before hand.
1) is that normal? Or at least ok?
2) could that be all i'm experiencing right now?

I'm not in pain anywhere and i'm not too nervous like I had been previously, though i'm starting to only because i'm not hungry and I want to eat. I haven't had heartburn. I'm not belching. I just don't feel hungry. I feel like a hypocondriac, and normally I probably wouldn't think too much because, like I said, my period just ended and I sometimes feel this way. But it's just the fact that I lost weight, and I really just want to eat normal again so I can put it back on.
Please, if anyone can help me ease my mind, i'd be forever greatful!
