Looking for a mom friend

Hey ladies I'm Katie. I'm 27, a first time mom of my 4 month old son and moved to Texas from Illinois when I was 7 month pregnant. I've always had a hard time making new friends and being a full time mom and working full time makes it even harder. The only person I have to really talk to when I'm struggling is my husband who probably thinks I sound like I broken record or calling my mom which isn't the same as being in person with her which has been hard on both of us but we moved here for a better life. My husband has family and his parents here and they are great but there are some things I know I can't open up to them about. So I feel pretty alone and trapped because I never leave the house except for work and grocery shopping. I'd really love to meet new people and make mom friends I just have anxiety when it comes to leaving my house but we could meet for coffee or go for a walk.
