Haven’t been here for a little while. I’ve felt so tired and mentally exhausted recently. I've felt distant, found it difficult to concentrate for long periods. There are times when I can feel quite jolly (as I am reasonably now), and that all is well with the world – then, suddenly..... I will hear or see something - often quite innocuous, and I just "drop" completely and/or become very depressed. I have had a lovely holiday recently, but so often, I just feel as if I want to sleep, and wake up refreshed. I really don't know is causing this. People keep telling me that everything is for a reason, but what I'd like to know is what is this reason? One other thing I’ve noticed, I seem to store things like telephone codes, road numbers etc. Could this all be because of this autism?
