please help me with this.

i keep comparing myself to other people- weather it's.. that person can get out the house, or that person has family, that person has a happy life, that person has something i don't,

how can i just be content with what i've got

anyone have tips on this, because it drives me crazy that i can't be content with any part of life, and though my life's far from perfict, surely this isn't that normal?. (or it is, bbut not to such an extreme?)
