I have always had some minor problems since my youth that came and went from time
to time. When I was in graduate school at about 23 I started to experience problems
with depression. I mostly ignored it hoping it would go away. And it did temporarily.
But it came back again. By 25 I started to get worse and worse. I started to have
major depression and occasional problems with my thought processes. I still didn't do
anything about it. At 27 I graduated from graduate school. By then my problems with
bipolar disorder were very severe so I finally did something about it. I saw a doctor.
He refered me to a psychiatrist who started me on medication. A number of different
combinations of medications had to be tried but after about two years I was much much
better. Now I have been doing very well. I still take medicine and always will. I am
thankful that in this day and age there is medicine for bipolar disorder. It is a gift
from God. God always took good care of me even when I was doing bad. He's a good God.
My advice to anyone who is experiencing depression or other problems is to get help
early on and don't wait a long time like I did. There is help. Here are a few links
where you can get more info about this kind of stuff.
