I really need to explain something that has been happening to me lately, and I realllly hope someone can understand, cause it is sooo hard to explain!

I have GAD... recently have got a lot better with meds and relaxing etc... but lately I have had this really weird thing happening.. I will try explain it as best I can...

This happens to me a few times a day.. I will be fine, have a really positive attitude, everything is good and right.. then all of a sudden its like I do a 180 and feel really different.. Its kind of like a low mood, but not sadness or anything, kind of like a feeling of dread. It is not a panic attack, but I do feel tight in the stomach and on edge and it lasts for a while, then all of a sudden I kind of find myself back to feeling ok.

I do not become suicidal or anything, just a feeling of dread or something, and all my positive thoughts of feeling good etc completely turn around...

I am so worried about this, I am so scared I have bipolar.

This wasn't happening before when I was having anxiety really bad... it's only since I have been improving that I have felt like this... Its not major, like Im not laughing one minute, crying the next or anything, no one would notice it.. its just a significant change in feelings inside me...

I would really really like to know if anyone has any ideas on what this could be?? or have ever felt this feeling...

The only thing I can think of is that maybe it is quite normal, but because I am paying so much attention to it.. that could be why I am noticing it so much??
I went through a period where I was really good, I didnt think of anxiety for days on end.. now I am waking wondering how I am going to feel that day...

Thanks

Kel
