First, you are having a baby and you need to care for yourself so you can care for it. A suggestion I have may be to become a member of a church. Get a good church, pray, let people know your situation. Speak to the Pastor. Pray for guidance. With the help of God, and His people, things can change for the good quickly. You are 20, you are an adult. You will be fine. You'll have to work hard, and you'll have to have tons of patience. Unless there is a physical problem and the doctor says that it keeps you from doing certain things, normal chores and activities are fine. Go slow and know when to stop. You can get a job to help save for the expenses of the up and coming baby. Be as independent as you can and you will be more prepared to care for your child when he or she arrives. The more independence you have and help from God, the less you will have to depend on others who may let you down. Hope this helps. God Bless and love that baby when it comes. Your doing the right thing to keep it.

It's hard to stay positive and motivated when you don't feel like you're getting the support you need. But you can definitely change your life because of your new baby, you don't need to stay stuck in the way you used to be. If other people doubt you can be different, prove to them that you ARE by your actions :) You can still do normal chores and stuff, just take it at a slower pace and be a little more careful as you move around. If you get concerned, your doctor can always answer questions about what level of physical activity is safe. The likelihood of miscarriage goes down dramatically after 3 months. Above all, STAY AWAY FROM THE BABY'S FATHER! If he beat you once, he may beat you again even if you are pregnant, even if it's his child. No matter what he says to you, the best advice is to stay away from him. If you are concerned about the smoking (and you probably should be), be sensitive to your familiy's feelings at the same time. They may feel hurt or offended that all of a sudden you care about smoking when you did not before, or they may not understand why you are concerned. You can explain to them kindly how smoking can affect a baby negatively and you want this baby to be as healthy as possible. But if you're rude or yelling, they probably won't listen to you! Or you can just avoid places where family is smoking at the same time. Remember, there is no shame in taking care of your baby and yourself and you should put that first. (Just be nice about it!)

If you are determined to keep your baby and raise it, go for it! Some resources that will help you alot are WIC, and I think Planned Parenthood sometimes has local programs. Especially for single moms. If you get extra outside support, it may help your family to also feel like you're doing your part to help the baby (even though of course you are already doing alot by carrying it around for 9 months!). Looking for a part-time job is a really good idea, because it will help you feel more independent and keep your mind away from worrying. Don't pick a job that requires you to lift heavy things, but there are lots of options. Jobs like secretary, call-centers, receptionist, smoothie maker (like Jamba Juice), cashier, ... You can sign up for free samples and coupons of formula from Enfamil and Similac's websites, and if you breastfeed (cheaper!) WIC will give you an extra food allowance to keep you healthy and making milk.

If it isn't working out, there is no shame to give your child for adoption, though it will be very very difficult emotionally for you to let go. My cousin could never have kids, so adopted 2 babies and is so full of love and gratitude for the Birth Mother! It is a huge blessing to allow another woman to raise the baby you gave birth to. When making a decision like that, pray to God for help making the decision and for peace. There are some good adoption agencies out there, one I reccommend is LDS Family Services, they worked with my cousin and with the birth mother - the birth mother got to read about and interview parents and choose which one she felt most comfortable with.
