Feel so low

I've felt so low for a few months recently due to some health problems and I hate how sad I feel and how scared/worried I am about stuff. Most days I haven't wanted to wake up but I still do and I try to get through the days but it's so so hard when all I want to do is curl up in bed and sleep forever. My boyfriend and parents have been amazingly supportive but I just feel so alone and sad. I need some words of encouragement right now because I can't stop crying 😔
