Feeling really tired. any advice?

Been to my doctors this morning and they said they cant fit me in until next week, I saw the nurse who did a wellbeing test and said I NEED to see the doctor.

I've been feeling so weak and tired lately, like when you are about to get a bad case of the flu and your body just aches, but this has been going on for nearly 2 months now and I've finally given in and went to the doctors, I was quite reluctant because their is alot of viruses going around but no one else seems to have the same as me or have anything as long as I have had it.

I cant sleep at night, I get about 3-4 hours at the most and I get such nasty migraines (which I am doing a trial for my doctor) My legs feel like they have heavy weights and it makes me walk weird too.

I'm trying to take things easy and hot baths do work but then it just carrys on a few hours later.

Cant wait for next tuesday :(
