I know the racing thoughts. I get them. I wish I knew what that was about but when it happens to me, thought after thought races through my head, to fast for me to stay focused and then I start racing around. I wash dishes fast, walk fast, smoke a cigerette fast... its a strange feeling and I dont know what causes it but I know that I it happens to me as well. I am going to bring it up at my next therapy session to see if I can get some ideas on how to make it go away or what causes it. Iwill post to you again with my findings. I go on Mondays to therapy so look for my post Monday. Maybe the sleep issues are caused by anxiety over your upcoming surgery as well as the eating issues. I have a daughter who has had multiple serious surgeries and for weeks before the surgery date I was unable to eat or sleep. I wanted to but was just never hungry, I was exhausted byt just couldnt slep. Wishing you the best on your surgery.
