Sorry Kathy, i forgot to reply on the portion about myself. I had a hunch that it could be anxiety or panic attacks. I have been looking into doctors, and will be making an appointment sometime this week. I do feel that this has all been triggered by the relationship ending, and the way it ended. I feel like i've also slipped into mild depression, because i have sudden outbursts of tears and crying for no reason along with loss of appetite, and dramatic weight loss.

Thank you for the links, and your help regarding this matter. I will be taking some time to read through them and try the breathing exercises too.
