Hi. New here

First, I am completely uninterested person (and my English is not good). I am only writing here because, I need to vent. My problems started in December 2020. I got positive covid test (2 weeks before Christmas). I was isolated in my room for week and half. During that time, I found out that, I was happier being alone. Everyday I saw memes and posts on social media that 2021 will be amazing. Well... they were not right. First week in 2021 I found out that I have paralysed right leg (doctors said that it could have been from covid). I stopped going to my school online lessons because, I needed to go to electrostimulations and rehabilitations. After 3 months my doctor said that my leg has started getting better, but on the same day my father died because of heart attack. I haven't seen for whole year because of his job. I completely locked myself from my mother, sisters and friends. When, I wanted to talk to someone about what happened to me or how, I feel, I found out that I dont have anyone. I kept this going for an year. This is my first time talking about this. I feel exhausted, and I don't know what to do. I stopped talking with my best friend, and I hate talking with my class mates because, I feel around them like uninteresting person who never has nothing to share and when he says something, it is cringe and weird.
