I can't enjoy anything, I've lost the passion!

I feel so stressed that I suffer from fatigue and nausea every morning! I feel like I've endured a lot in the past two years and everything has gone against my expectations, I can't enjoy anything, my time is wasted daily and I'm not doing anything for myself, I don't have the passion to change anything despite my strong desire! I eat a lot at night and I have bad dreams, I pretend to be happy and inside me is miserable, and in our society they do not believe in mental illness and it is getting worse
