This has been the story of my life. I've been on and off different medication for years. Some work some don't. It takes a long time to figure out when it does or not, usually several months of stepping up the dosage to see if it works. Then several months stepping down when they don't. Suddenly a year has passed and I haven't been able to do anything constructive because the constant ups and downs has kept me in a paralytic state.
I've finally found some medication that seems to work, but it has taken me three years to get there. Suddenly I face having to go back into the real world and getting back to school and work. It scares the living crap out of me, but I know once I go there things will light up.
I'm really trying to turn my life around. I've started to exercise and I'm more social than ever. I'm really starting to see some kind of light at the end of the tunnel, but this is me talking in an up period. Just a week ago I had a down period and just wanted to die. Luckily my meds help stabilize my mood swings, but I still have them occasionally.
My advice; Get help immediately. Sitting at home doing nothing only makes things worse. Yes it's risky to start taking medication, but without taking risks you'll get nowhere. Anyway, the alternative is much worse.
