I'm tired of everything

I remember when I was 10 to 13, they were the best years so far. I had so much self-esteem, so much charisma, I was so sociable, happy, but since the pandemic, all that has changed. I have become a quiet recluse and this is consuming me every day. I want to make friends, talk to strangers and stuff like that, but honestly, I have simply forgotten how to socialize and this is making me so sad that I simply can't do anything anymore. I don't want to tidy my room anymore. I don't want to tidy my house anymore. I don't want to draw anymore. I don't want to make music anymore. I am simply losing everything that makes me me. I downloaded Reddit with the intention of finding people like me, but oops. I am shy, even online. I don't know how to talk. Every day I am descending deeper into my pit of sadness.
