Sounds like an anxiety problem. You may need to see a psychologist to assess your need.
A few years back I had a problem to where everything made me feel as though I was going to die soon. I'd have panic attacks,breathing problems, I'd get really scared out of no where. I was scared all the time, I couldn't eat right, I couldn't sleep, and I was extremely irritable.
I talked all of my suppressed feelings over with a doctor, researched ways to get better, and took a medication that balanced my hormones. I feel much,much better.
Here is a site about panic and anxiety.It may help! Hope you get better ,sweetie! You can do it!
