My friends got really distant during my first pregnancy too. They know you can't do as much and once the baby arrives, they are afraid to disturb you. Be patient w them, and like the above comment, try to find groups of other moms.
Birthing class was awesome for making friends. Most hospitals offer them free and it's a place to be able to open up to others who are going through the same thing.
Thank you for your advice. I probably have been isolating myself it will probably help a lot by finding new people to relate to.
Sorry for the typos I am on my phone...
