New Here

I've recently been diagnosed with combined ADHD and am struggling more with the diagnosis than I thought. 
I had known for a long time there is something different about me, and it's a classic case of being a hyper child into becoming an adult that has internalised it all. 

I've found recently that my focus and concentration have gone really badly down hill, and i'm now finding more and more things to get distracted at work. I feel mentally drained, like I don't have anything left to give, but I can't afford to be off work, and don't want to let my company down. 

I hoped getting a diagnosis one way or another would help, but it hasn't just yet.
