I feel constant sadness all the time, i feel like my brain doesn't produces dopamine anymore, i basicly don't enjoy anything i do

I want sleep all the time, i feel like i have no energy to do anything.  Having hard time geting out of bed. Whenever i need to do something, i get sleepy and doesn't really want to do whatever i need to do. Also i sometimes doze off during the day even though i sleep enough.

I often feel so much frustrated at myself and hating myself because of things  i did wrong at the past or recently. I see my self as a failure  and can not stop pitiying my self. This impacts very negativly my selfesteem

I have no energy to communicate with people anymore. I have no caring friends and none of them initiates anything with me. My friendships are always one sided and that makes me feel awful and unvalued

I feel like my brain is sleeping. My reaction time at certain things are slowed down drasticly. I also can not think and act fast. Feels like i have fog in my brain
