Anger within myself

Assalamualaikum!

If a person is angry with his/herself what dua is good to read? Sometimes, I feel quite angry with myself and it stops or delays me from doing some things that are important such as; studies, prayers, helping out in the house...etc.

Instead I watch a movie/tv to make me feel better (which obviously increases my laziness) or annoy my siblings (not in a mean way at all).

I do read quran, but i feel bad to read it in anger, if u get what i mean.

Any advice?

jazakallah khair

p.s forgive me if i posted in the wrong forum thingy
