Can someone help me please ??

I'm just gunna say straight away now it's gunna be a bit of a touchy subject for me to talk about. Basically i am in my final year at school and my GCSES are on Tuesday and I'm scared and I suffer from anxiety attacks and panic attacks. Lately they have been getting worse but my mum has had to keep me off because a girl from my school is bullying me with a few others and its been a rough patch for about 6 weeks. I'm also very shy and insecure about my looks but my boyfriend had been helping me with it. But I'm just gunna put a pic of what I look like on here and I just basically need some positive thoughts on what to do teachers have been made aware of my situation and so have my parents and I don't know what to do anymore.
