I have had a few things wrong with me. I've had a cold that's lasted a few weeeks nearly 3. I'm always tired yet struggle to sleep well. I have 2/3 mouth ulcers- one of which is unbearable and proving hard to talk and eat without being in a lot of paid. I also have a weird headache that drifts in and out mainly in the evenings. My eye sight keeps going blurry as well like once a day. I'm really lot feeling myself- massively unmotivated. Any ideas?
