Not getting enough sleep does a number on me, too.

What helps me (in no particular order), so, maybe some of these might help you too:
benadryl
valerian tea
mindfulness meditation
warm milk with honey in it and some bread
exercise during the day

What Verbascum said, also. When I feel the way you describe, it really helps to just slow down and take things one step at a time.

Take care. I hope you're feeling better by the time you read this.
