Motherhood is so lonely

I don’t feel like I have friends tbh. Everyone I was close to i can no longer connect with. My life revolves around my child so I literally have nothing else to talk about besides my child’s growth, milestones, etc. My friends are living their single, partying life. I feel like things have changed so much. I feel so lonely and depressed. The only mommy friend I had was my SIL who moved an hour and a half away and is busy with her kids so we rarely text. I’ll feel okay and like I’m fine and then I’ll see videos of my friends hanging out and I’ll feel so alone. To make things worse, my husband and friends never really got along so I always felt like I had to choose. Now that the baby is here, he doesn’t feel comfortable then being around the baby and bringing any negativity near her. It just sucks. I need mommy friends. I need to socialize outside of my small circle which is just my husband, baby, and parents. Motherhood is so lonely.
