Medication help

Amber

Hello! I would love some help with this! I am 15 yrs old. I take fluoxetine. I'm on this for social anxiety and sleep. I resently (about 2 months ago) just moved up to 40ml. But I was wondering how do u know if it helps? And also, I've been depressed and suicidal lately. But its not from the mess it's been like this for 4 years. (Had this med for 1 year) wondering if I should take something else or take an even higher dose?
