Aww poor you, nothing that I can say to you that will make you less scared. I am keeping fingers and toes crossed for you that its good news for you tomorrow, you obviously have some symptoms, so you do need to have a proper diagnosis, you need to know whats wrong and hopefully something can be done about it to make you feel better once more.
Dont give up hope, dont worry ahead before things happen.
Not nice to feel scared!! Being scared will not change the result so try to stay calm! (Easier said than done!)
I will keep my fingers crossed for you!
