Occasionally I will get these 'attacks' where I get very anxious and shaky. I also get really irratable with everyone and won't speak to them. For about half an hour. And then it will change and I'll be all happy and feeling confident and will talk to anyone about anything, even if it's embarrassing. While I'm like this I'm still shaky and irratable. My thought patterns change every half hour or less when I'm like this. One minute I can be feeling really confident the next minute I can feel really self-conscious. It lasts for a couple of days to a week. I also get heightened senses - like I will see things in the corners of my eyes or be able to smell things more clearly and hear things that I know aren't really there. I've been to see psychiatrists about this but they just brush me off telling me it's nothing. I go through hell when I'm like this. It's like my thoughts are being pushed and pulled both ways. I can also get bouts of incredible anger when I'm having these periods. And these periods will happen about ten times in the space of a year. Is this anxiety? I get episodes of pure depression too, where I just feel empty and drained with no emotions other than sadness.
