Confused: is anxiety the culprit?

[Boy_Wiz]

Hello! Been reading the forums for a while now (helps reassure me I'm not going crazy!), and decided it was time to post a question I have. I've got a hunch the answer to my title is "yes," but I'll explain my situation.

This fall, I felt fine. Had no issues with anxiety. Was studying abroad and had a great time. When I returned home, I suddenly became "sick." I was worrying about my health again (this has always been a bit of an issue), and convinced myself something was wrong, as usual. I wasn't eating as much, and just felt a bit in the dumps. After a week or two, I recovered for the most part, and things were fine in January. February, I realized I had lost some weight accidentally (~12 lbs.). This is fairly normal for me, and I chalked it up to not eating enough. I frequently have issues keeping my weight balanced. It either accidentally goes up, or accidentally goes down.

I quickly got anxious about this and, from what I remember, started trying to stuff my face at meals. It was uncomfortable, the amount of food I was eating. A few days after realizing I had lost the weight, I had issues not feeling well again. What happens is I wake up with a mixed feeling of hunger and nausea that can't be sated. Eat something bland, still hungry. Eat anything else, feel more nauseous. By around 10 o'clock or noon, I felt better and was able to eat normally. During this week, I gained 8 lbs. (hooray!). After that week, I "recovered," and have since felt fine and had no problems eating or keeping up my weight until two days ago.

Starting Friday, I woke up feeling nauseous/hungry again with stomach cramps and just feeling crappy. This time, it got worse and has been basically persisting all day. Last night I got hungry around 8:30pm and had a meal, and this morning I was able to have some eggs and bacon, but other than that I've been making myself smoothies to get enough calories. I am getting hungry again this evening.

During the past three weeks, I've also been dealing with intense anxiety. I couldn't get myself to board a flight once, and had to fly home the next day. I've been obsessing over my health again, and just feeling really uneasy and preoccupied, unable to concentrate. But the past 2 days up until today, my anxiety seems to have vanished, and I'm just left with this malaise.

Am I going crazy? Is this anxiety? Should I check in again with my GP?

I'd appreciate your thoughts!!

EDIT: My dad is a doc as well, and he sees nothing wrong with my problems. He says my symptoms (weight loss, loss of appetite) aren't significant, but rather that they're among the most common complaints to doctors. He says that they especially shouldn't be troubling because they come and go.

Thanks!

Well, I decided to go into my GP just to be safe. He's really understanding when I come to him for medical advice. Plus, 4 days with very little/random appetite is enough of a reason, I think. I'll let you know how that goes.

The good news is that, though I still felt sick this morning, right now I'm really hungry and going to eat some bland foods! Hopefully this lasts all day!
