Maybe the moderators (if they decide) could format this as a list in some better way for us all.
Lets make a list of ways we have found to make ourselves feel nice and comfy instead of horrible. Include or add only things that you think others might find useful also. Try not to make each 'way' or nice thing too complicated and not long descriptions. Here are some of mine:
Watch a film, YouTube, or other video that always puts you in a happy and contented mood.
Choose a healthy food or drink you truly enjoy, (maybe a certain fruit, salad or meal or a small amount of chocolate or coffee) Use sparingly as directed for the symptoms of gloom, doom, and other nasties. (WARNING: If you can't resist the temptation to eat too much of it or it leads to other overindulgence, think of a different one.)
Excuse yourself and take 15 minutes to sit or lie in a quiet room (Headphones or a trip to a quiet garden or library corner may be necessary) While there, just let your body BE. You can think about anything that makes you feel gentle and calm.
Listen to your favourite CD or MP3 with your eyes closed and REALLY listen to it for full effect.
