I Am Sick and Tired of Being Sick and Tired

So today was the day I was finally diagnosed after a long 5 months of an undiagnosed illness which the doctors thought was all in my head. I 100% knew something wasn't right, I haven't been feeling myself at all for months now. 2 rounds of blood tests had come back normal which I'm pleased about but also frustrated as I wasn't getting any answers but my third round of bloods came back strongly positive for mumps and glandular fever. After months of worrying I was going to die of a terrible disease I've finally had some peace to my mind. When your not feeling yourself don't ignore it, keep going back to your doctor. It took me all this time to get diagnosed, I was on the verge of a mental breakdown. I couldn't cope, but the one awful thing is the damage has been done. It's made me so anxious and depressed that I just feel nothing.
