anxiety
"Rode the depression roller coaster for several years, and after series of traumatic events in my early 20s, I lived in such a constant state of panic, I could hardly leave my house. I was Diagnosed with Generalized Anxiety Disorder at 26. I tried an SSRI with no success. My doctor prescribed propranolol (20mg, twice a day) and while I thought it was a long-shot, I gave it a try. I felt a change within a day or two: naturally relaxed, not drugged or drowsy or high, or anything weird.
So here I am, 18 months later, fully functional and feeling 'normal'. I do get slightly anxious on rare occasions, but it's nothing that stops me from taking care of business."
