GCSEs form a nerodivergent

Hay so Im neurodiverse. And I would just like to mention I have been officially diagnosed - privately. Like I have really really severe dislexic, dyspraxic, disgraphic and dyscalculus. It's so bad I should be able to read, write, talk and shouldn't be in a main steam school. And definitely not supposed to be able to GCSEs but I am. I don't know how nor do those who diagnosed me. And I'm panicking a lot. I can't breathe properly.I feel so alone. I fell guilty when I'm not studying and I can't stop felling that way. I'm just so scared. And I wish I was different. And I'm just so angry too. I'm so tired . And I came on this app for any advice to stop me panicking so much about everything and honestly to fell not so alone too. I have no idea if I'm going to pass my exams. And I know those with dislexic are not stupid but I fell as though I am. Some people have dislexic and they get 9 and stuff but for me thats just never going to happen I'm barely passing. I got my English lang paper 2 tomorrow and I'm so so scared. Plz I need your help.
P.s plz no hate comments iv never posted anything online before and I'm really scared for that also.

heyy its normal to feel nervous about exams and thats coming from an a level student that has been through GCSEs. i can confidently tell you that it may seem that gcses are the most nerve wrecking situation to be in, it will almost be completely forgotten when you leave that exam hall. if you are stressed ask perhaps for extra time and maybe a teacher to give you one on one help. also alot of youtubers do quick summaries that you can listen to to calm down your nerves. trust me when i say its not worth beating yourself up over gcses. do the best you can dp. i believe in you. best wishes with your exams.
