What it means to believe
KT,
I feel for you. not getting proper sleep as you know, is not good for you. I agree with Red, consider Davit's advice, he really knows what he is talking about with this.
Relaxing techniques, I admit, i watch my favorite show before bed which I know all the advice is to not watch tv. but i make sure it is something comforting. the tv equivalent of mac and cheese. :) Don't underestimate a warm bath and anything else you find relaxing.
I also bought a herbal pill "relax and sleep" at the drug store and used it for a while. it has the same thing as sleepy time tea - basically catnip and chamomile. the catnip was a bit too much for me, but it did help me sleep. it is worth a try. you'd know right away if it doesn't work for you.
It is really hard to let go of the worry about something like being able to go to sleep. it can consume you and feels like a vicious circle, you worry about not sleeping and this prevents you from being able to get to sleep. i feel your pain on this. again, listen to davit, and try to focus on anything that helps you to feel relaxed especially before bedtime.
Keep posting here. I posted A LOT when I tackled my first few negative thoughts / worry. I was out of touch with how to relax as well. It gets easier. Posting a lot is welcomed here. you are not alone.
