Life, location, and disillusion

Sometimes I wish I were anywhere but here. At times I wish that I had a different life with different friends just to know what it was like. And then there are times when I wish I had a different life because I become disillusioned with what I have. Would life be different if I weren't here? Would the disillusion be less potent in a different place or in a different life? Probably not, but I still wonder.
