Having a valid and complete support system is extremely helpful when having children. Stop associating with people who bring you down or who are going to be a negative impact in your children's life. Even if its someone who has been your friend for a long period of time, its not worth it. I've watched too many people ruin their children's life by holding onto people who are not trustworthy or who try and trash your abilities. I've had to let go and move on from people who were once close to me. Its hard, and it sucks. But its been better. Less drama, more time for positive influences.
