I was diagnosed a week ago with depression, and my therapyst said that I may have to take pills to treat It.

Taking pills for my depression scares me a little, someone here who takes them can explain to me:

How does It feels?
Did they help?
How many time you had to take them?
How many time takes to make effect?
It messes with your brain?
You still feel like yourself taking the pills?
Do you have some advice to make this process easier?
It's best not to use them?

Help please, and thank you.
