Lion and Lambs

Stumped. I don’t understand how a downright pesimist can have no comprehension of depression and yet I, as an optomist, can be so haunted by it. This friend of mine is negative about most things, situations, people, etc. Listening to her is often draining because everything is so negative. However, she walks through life, though full of worry, totally oblivious to depression, or how it affects people. I choose to look at the positive side of things, or try really hard to. Still, I find sadness darkening my doorstep all too frequently. I guess it is one more example that just thinking something hard enough doesn’t make it so!
