C.O.
work is not a break.
Unfortunately - motherhood is not all it's cracked up to be and now you have to put your son first - that doesn't mean you don't deserve "ME" time - you do...
hire a sitter. get out and do something for yourself - be it a manicure or a pedicure...
Find a mommy group with your church and see if there are any other young mom's out there that can help you and maybe you guys can start sharing babysitting...
I'm sorry you got pregnant so young...I applaud you for handling it and taking on the responsibility....it's NOT easy.....I'm sorry you don't have family or friends...I would also suggest going to your local library on the weekends - even Barnes and Noble and Books-A-Million have groups that get together...you'll be able to find like-minded people and get the respite you need and deserve.
