Autism and Waiting


I have a really hard time waiting for things. I can handle waiting small times like 5 minutes but anything longer than 20 I struggle. Long waits are especially difficult. For example, I am waiting for the outcome of my ECHP and whether I get one or not and I am constantly on the verge of a meltdown with all the uncertainty and waiting. I am trying to get an NHS wheelchair - more waiting. Seeing whether social care can help me, MORE waiting. I am not coping and I'm always anxious and fretting. 

Is anyone else like this? How can I be more patient and not stress so much about waiting?
