I'm Venting

I've been diagnosed and started treatment. What do i do? Because of my treatments 'm unable to work, and I've become scared of simple things like people sneezing or coughing because i don't know what could happen..... I'm normally an outside, hands on person and now I'm afraid get a small cut or the flu. I am aware i over think but isn't that a good thing? Should i be extra cautious with everything?

So maybe instead of what do i do maybe i need to start thinking about what can i do? I play video games, go for drives and if its a good day I'm on the beach. I've tried playing Guitar and drawing, but one of the problems of being 19 is that i still don't know what makes me happy.
