I am 19 years old and not even 5 ft tall. Basically, I'm very small. I went to the doctor for an upper respiratory infection due to neglect of my asthma. My doctor gave me a prescription for 3 20mg tablets of Prednisone per day for 5 days. After taking it the first day I started experiencing high anxiety attacks, insomnia, and began to entertain suicidal thoughts. Thinking it was all due to stress, I sought help after taking a total of 300 mg and come to find out that the prednisone may be the cause of everything. We are not sure yet if this is true, because the drug is still in my system, but all clues point to that.
