Sad SAHM

I shouldnt feel this way! Im sad! I feel like a worthless failure. I have two beautiful children that i love more than life itself. I always feel lonely even when surrounded by ppl. I feel ive lost myself. I have no friends, no one to talk to, no one to vent to. My life literally consists of taking care of my babies, household chores, errands and sleeping. Im tired of feeling this way, how do i make time for myself?! Being a stay at home mom def has its cons
