Hey guys!
First of all: English isn't my first language, so sorry if there are any mistakes!

My mental health has been really bad for about 3 weeks now. I barely sleep, am always tired and especially after I wake up my mind is going crazy and I start ruminating over the same topic over and over again. 
The more time passes the less things I do. All my hobbies I loved... Idk I don't feel happy to do any of them anymore. Whenever I think about doing some of my hobbies I get anxious because I am afraid I will never like doing it again.
It's driving me crazy and I am so afraid my passion for all those things will never come back.
Same goes for my friends. I don't want to meet them. I just wanna sit at home and don't see anybody because when I meet one of my friends I get sad because I feel... Idk how to put it... I feel sad because I can't be happy like them and can't share any of our interests with them atm
I just feel so numb. Even cuddles with my cat won't brighten up my mood. 

Has  anybody felt the same before? Can I ever get back to normal and enjoy my hobbies? 
I really just want to be my old self who was happy doing stuff like sewing, drawing or watching anime etc. :(
