I no longer stay home full-time with little ones, but just wanted to share a bit of encouragement. I've definitely been in that place a few times, feeling a bit lost. It's easy to lose your identity when you stay at home with a young one. You become "just" a mom and wife and house cleaner. It is so, so important to prioritize some things just for yourself. It will keep away depression, and help you connect with others. I would suggest joining a gym, a mom's group, or a hobby group. Most gyms have wonderful childcare options, and you can meet a lot of new friends, plus get in shape (improving your self-esteem) and stay energetic for your family. And many hobby clubs (scrapbooking, knitting, church choir, etc) are filled with other moms who can help you figure out childcare.
Another option for personal growth and connecting, is to take a class of some kind. You may be near San Jacinto Community College, or one of the branches in the Montgomery County Community College system. They have great non-credit classes (ones just for fun!) that are affordable, and also offer childcare.
Good luck and God bless!
