I Feel Like I Can't Get Anything Right, My Opinion

I feel like i can't get anything right, my opinion doesn't matter i will always be wrong. i feel i am connately searching for approval from other scared incase i upset anyone. feel very emotional when listening to music. i swing from one extreme to the other one day i am happy the next I'm low and upset and don't know what to do with myself. I'm at university at the moment ( I'm dyslexic) and feel i am stupid. recently i am at breaking point i don't know what to feel, to be honest i feel like dropping out of uni and curling up in a ball.
