Working full time as a teacher?

Hello,

I just got diagnosed with fibro about a month ago. I also just graduated from grad school and began working as a teacher. I'm afraid I'm not going to be able keep working as a teacher. I love the kids and the job, but I'm truly not sure if I will make it through this year without getting bedridden again. This week was rough, but I managed to make through okay. Are there any teachers or others who work full time who manage to keep going? Thank you in advance for any help!
