Hi everyone. My name is Robin Lorentz, just turned 23, and I'm from sweden so please forgive my for any incorrect spelling

I don't like to ask for help from strangers but I realize that I need help now

As it is right now I'm studying Englsih at university but I'm struggling hard to get over my very low self-esteem which gets in my way all the time. It's terribly hard to even open my books or write essays when the sublimial mind says that I won't make it...
I don't know what can be done about that but I ask anyway for help in some way...if it can't help my mind then my body needs it. It's tired beyond exhaustion.
Thanks
