Antidepressants

I'm only 14 and I honestly don't know who to trust this with at the moment, so I need help. My parents think I've been on my antidepressants for over 8 months but I stopped taking them 4 months ago and today we went to visit my psychiatrist and he basically said that I can't "get of them" until December and I'm sick of lying every morning my mom makes me take it so I put it under my tongue and spit it out when she walks away (i sound like a basic teen from a movie ik) but I'm sick of having them control my feelings ANYWAYS I don't know if I should tell her or would that make her even more mad bc I've been lying. they base almost everything in my life of of the fact that I have these problems. Today he said that if my mom wasn't happy with the results of me getting off the meds they could make me I DONT KNOW WHAT TO DO PLEASE HELP
