You did not mention the ages of your daughters, but there are several organizations (all have area chapters) that might interest you: 1) Mocha Moms, http://www.mochamoms.org/
2) MOPS International, http://www.mops.org/
3) Moms Clubs, http://somd.com/orgs/women/mothers/index.php
4) GHEM, Godly Home Educating Mothers
If you do not want to join a group, you should look for activities where you can take your daughters and you all will meet other parents. All local libraries have storytime sessions; Nature Centers offer special workshops for children; bookstores like Barnes & Noble and Borders offer special storytimes; and local museums. When the weather breaks, take them to the park and you'll find plenty of parents out with their preschoolers. During this time, your social life will pretty much include your children. It's just that season of motherhood until they are older. So, find those activities you enjoy that embrace children. Some art supply shops, like AC Moore, offer Saturday clinics, and some new art studios offer classes for very young children and mom. There are yoga studios and gymnastics programs through park and planning, and even Kindermusik offers a Mommy and Me playtime. It just requires a shift in the me-time mindset. You do not lose who you are because you will share that side of yourself with your children. For example, I love museums, reading, restaurants and travel. I drag my children to all of these activities, trying to find things that also offer educational opportunities for them. My husband loves music and technology and takes them to those events. And, our children LOVE rides and games so we take them to places like Chuck E Cheese, state fairs, Six Flags, etc. Some places like My Gym and the Little Gym offer Parents Survival Nights Out so you can get some time to yourself. You do not have to be a martyr. And, once you make good friends (over time), maybe you and another mom can take turns watching each other's children so you can have some quiet time. If you have relatives in the area, they might also be helpful so you can get a day to yourself, at least once per month, and/or talk to husband about taking one Saturday a month when he can spend time alone with the girls. That way, you'll get two to 3 days per month just to yourself. Also, learn to wake up before your children, or stay up one hour after putting them down to bed, and that gives you some more time to yourself! You can be a SAHM without losing yourself and be totally fulfilled, and you should have good, I mean good, friendships, which take time. Do not invite women over as soon as you meet them. Time is a person's best friend. It might be a year or two before you start inviting someone into your home or allowing them to watch your children and reciprocating. But, you need time to get to know people. Never make relationships out of desperation. And, in time, you will have a lifestyle that is fun, gives you time with your family and a new appreciation for time. Always try to continue to learn something new, a new recipe, new hobby, new language, and be sure to teach that to your girls. There is no such thing as a perfect wife or mother, so just do your best. Try to ignore foolish conversations like "why are you home? and When are you going to get a job?" Do not try to fit into a bizarre "Stepford" wife for your husband, meaning you are perfectly dressed and house is perfect, etc. Just be yourself, but be willing to let go of some of the freedom that comes with being single without children. It's only for a short period, believe me. I've been home five years now, and it seems like a blur. Also, do not neglect your spirit nor your physical health. Make time to meditate (as a Christian, I pray), and exercise your body, either by takign your girls on walks or riding bikes (in the winter, walk indoors at museums or malls, a mommy & me gym, etc.) This is an exciting time in your life. Embrace it and enjoy it. There are few times in life when we actually get to stop and live in the moment.
