be less judgmental

I find myself judging people over stuff that i probably shouldnt. for example: almost every girl in my family is married and having kids(even the ones barely turning 18.) im 22 and constantly think stuff-well, stuff i dont even want to mention bc its so mean!!! and i feel horrible about thinking these things and im trying to be happy for them…its just hard on me. so im trying my best to be less judgemental on them, and others out in this world.
