Any advice would be amazing thank u x

hello, i dont really know why im feeling so unmotivated and i have no energy for anything anymore, i cant sleep properly, im not eating as much as i used to, all i want to do is lie in bed, i dont want to leave. Im having these bursts of anger and i dont really know why. Im having thoughts of unworthyness and if i deserve to be here. Everything is going great in my life, me and my family are closer, i have new friends, i have a job and its going really well but i just dont understand why im not happy.
