Is it normal to feel this way/what should I do? Please help.

Just follow the medications.
I went out with a girl once who did not notice that when she was off her meds she was a mess.
As soon as she went back on her meds she was right again. Although SHE herself did not notice the difference.

At your young age you already have enough to contend with, so even though you are opening up here, a good friend or ideally parent, would be your best option. I'm sure you are well loved but I understand (as I'm sure they do too) that sometimes you may seem a little irrational at times.

I already feel compassion for you about you going to a hospital, I'm sympathetic to your needs and I don't even know you :)
It is an awkward time for the most common of girls out there, my best advice would be don't make any rash decision, seek help from your support people around you.

Oh, and I was thinking about my 'last paragraph', just telling you stuff won't fix you! IF you feel like hurting yourself you can post back here (then wait Lol hopefully I see it) or don't actually 'wait' but call someone immediately or go to someone who loves you to get support. Most of the time we just need a hug and shoulder to cry on.
