I need help to cope

Hey everyone my name is Mikayla and I am 22. I am married & have a daughter who is 17 months old. I been having headaches that last for days no medicine can help with. I finally went to the doctor letting them know and ended up getting a cat scan. my results came back as I have a growth on my brain I have to get an MRI to see if it's growing or it's old. to say the least I am so scared. I had a heart to heart convo with my hubby but I am having such a hard time coping with it. has anyone gone through this? :(
