Can I have some advice on how to 'hang in there'?

Sounds like you need to find a counselor, if you attend church that's a good place to start and you won't have to pay for anything for counseling with a pastor (or you shouldn't). I'm sure how much to say because some things may just cause you to get deeper into a funk, but I try anyway. First, please don't offense to anything, I am not a hold-your-hand and pat your head sort of person. You need to realize that being pregnant and having a baby means thinking about that child first and foremost and that baby really doesn't care about your plethora of excuses for your actions, that child needs you to get up everyday with every intent on doing what's best for them. That means, eating when you know you are supposed to eat, if you can get a small fridge to keep in your room away from others and keep it stocked... if you can't hide away fresh fruits and veggies and things like granola bars and nuts and healthy cereals that don't need refrigerated. Go for a walk everyday, fresh air does wonders for your mood. If you want the house clean get up and start making an effort--- it's tough, I'm about the only person who cleans in my house and whenever anyone lifts a finger they practically need a parade to commend their efforts, but I have a son living in this house and I don't want him around filth so I do it myself. You just gotta wake up and decide you are done making excuses for yourself and do what you can.
