I suffer OCD and in the past depression. This was very prevalent when I was young.
At age 14, I didn't know what was wrong with me, and thought I was mad, so tried to hide the symptoms from everyone - this was very tiring to say the least.
Now, nothing makes me think I'm going mad - because I know what signs to look for and tend to catch them before they escalate. I've been completely fluoxetine free for almost 4 years and can't see myself going backwards now...
I do wonder about a lot of people around me though......
my advice for those who may think they're going bonkers is to talk openly to someone you trust about how you're feeling, no matter how weird it seems. Another viewpoint on the situation may be all you need, or perhaps just a bit more support?
Talk it out - that's what I'm saying, I guess!
