pandemic with anxiety advice

I have a pre-existing anxiety condition and I have to deal with it on an everyday basis. This pandemic and everything that is happening around me has made it almost unbearable. I know it is hard for everyone but I have convinced myself this is the end of the world. Nothing seems to be getting better, I can’t see any of my friends, my mother has to live in a camper outside of our house cause she still had to go to work and is possible exposed to it just so she doesn’t infect me and my dad. My dad and mom both smoke and are older so there is a low chance they would survive this virus. My friend believe in conspiracy theories and has put the thought in my head that someone made this virus and it will all end in a purge where we die. I am constantly terrified and depressed to the point where I cannot do my schoolwork online. I am so terrified of dying, or even worse my mother or father dying. I just want life to go back to normal and everyday I feel more and more like it never will and that this is how it ends. I don’t know what I want, I guess some advice or some comfort or someone to tell me I’m wrong.
