Gift from god symptoms and conditions

Started taking sinulair about a month ago and I thought it was a gift from god...it worked great! I have depression anyway (controlled by meds) and noticed that things were going downhill moodwise about 10 days ago. I'm stopping it today after going online and seeing all the people who've had "moodiness" and depression....for me it could start a tailspin I can't risk.

Six weeks ago, I took prednisone for ten days for joint pain and swelling (both hands, both knees, both feet etc. ). the swelling subsideded the fourth day. I lost 5 pounds of fluid weight gain. Ten days after stopping predisone, I had a second onset of swelling and pain with 5 pounds of weight gain. I took 40mg two days and lost the 5 pounds and severe pain. I also lost depression that has been with me 45 years. I experienced elation sustained for the first time since I was 18 years old. I am 63, retired, blessed with a good life within a prison of secret depression. I cut the dose to 10mg per day and saw a rheumatoligist who ordered 15 blood tests today and continued the 10mg dose. the elation continues and is joined by high energy. Is this a gift from God or what? Fred
