Need advice

I’m currently a stay at home mom .My daughter was born in October so I’ve only been doing this for 6 weeks now . Some days I feel like I’m totally going to lose my mind .my boyfriend works 10 hours Monday-Friday and when he is home is trying to sleep , I stay far away from most of my friends and family so no one ever comes over and plus Covid! I’m still young, I’m only 18 and I still haven’t even finished school and I try hard to stay motivated but it’s just so hard . So I would just like some advice how I could do better in my life
