About depression..?

Question

( Pay no heed to my last question I posted, this is kinda different. )

I hear that there's a chemical in your brain that makes you have depression. Not sure what it's called or how it works, I just remember my mother talking about it one day. I asked her the question I'm about to ask, but I don't think her answer seemed right for me.

If it's a chemical that causes depression, and antidepressants help to reduce that (or something like that), then how come that when I'm happy and not depressed, when I think about anything related to depression, angst, harm, such. I get automatically depressed? I can also force myself out of it, but it kind of gives me a headache afterwards.

Just wondering. o.o;

I really don't remember anything that would cause me to get depressed ( such as a tragic event ) because there never ws one in my life. I used to be a happy and cheerful kid, until I turned 13 or 14.

Actually I have very long bouts of sadness and depression. The most I had was up to a full week of just depression. It was killing me at school, too. x.x; But yea.

Answer 1

There are several chemicals in the brain that can be related to depression, serotonin is just the biggest one. Depression comes in all sorts of different varieties. Plus, clinical depression is very different than what some call "the blues", or just feeling sad temporarily, which is what you are describing.

Answer 2

Depression can be caused due to a chemical imbalance in the brain or due to a tragic event that left you devastated.

Answer 3

Seratonin levels can affect your mood. Anti-depressants regulate the amount of saratonin released.
