I hope my life experience in this area will help you, but I am also a stay at home mom. Currently, I am busy with homeschooling my 10 yr. old daughter and housework and all that, but when I was single and at home a lot when I was single, I too was lonely. Let me explain.
I first moved out of my parentsā house when I finished nursing school and I went off into the Air Force. It took me to another state. I lived in an apartment and I worked 12 hour shifts, so I would get four days off at a time sometimes. I didnāt know anyone at first. I was so lonely. I did have a car though, but I hated eating alone or really going out alone. I would call my mom, but I had to watch my long distance bill. I was very lonely when I didnāt work and was sad a lot. I did join a gym finally and went and worked out daily and that helped, but I came home to an empty house. I got a puppy and that did not fill the void either. This was the time, I finally found Jesus. I knew God and had a great love for Our Lady, but I had protestants bothering me if I knew Jesus and you know I didnāt. I got to know Him. I would talk hours alone in my apartment to Him, getting to know Him. I would read the Bible to know more about Him especially after my protestant friend told me there is a difference in knowing about someone and knowing someone. I knew about Jesus before hand, but I did not know him personally. At times when I could not pray, I would just say His Name and feel better. I thank God now for that time of loneliness. I was discharged from the Air Force and moved back home for it was a medical discharge. When I tried to re-train into another career and go back to school, I choose Theology and went to the Franciscan University of Steubenville. Again, I was alone, but this time it was different. I never once felt alone. I knew Jesus was with me always. He was a friend that I had always with me. A friend that went everywhere I went. I went more to Adorations, but when I could not go, again, I spent hours praying alone in my apartment. These were years of spiritual growth for me.
So take that loneliness, and boy I know it can hurt, and use it to become closer to Jesus. As you come to know Jesus, you will know the Father more and soon the Holy Spirit. That is how it worked for me, but everyone is different in how God moves you and works on you. When I first got married, we were a one car family too and my dh had to take the car to work. I was left all day home alone in a very small military apartment. He was in the Navy. I did not feel loneliness there either. Once you find that Perfect Friend who is with you always, you will not feel loneliness. Do you need to talk to a human being? Yes, and I did. There is nothing wrong with praying for friends. I did not have many, but the few the Lord put in my life, were like precious jewels.
Another suggestion too is take some long walks around your neighborhood.
I will pray for you and your intentions.
