It is hard to imagine some times, but some times just looking at pictures can help..

Some times at work when I am having trouble and need a real thing I guess.., I use a picture of my cat-- he is a real thing, I pet him every day,... A picture can spark a *good* *calm* memory of me with my cat...

I don't know if you have an animal or not, or something like that... some times places that we have gone (a good vacation) could help....
