I’m a FTM and feel like I’m failing miserably😭

My sweet boy is 5 months old and I’ve been blessed with the best baby! He’s so happy and giggly. But idk why but these past couple of weeks have been so hard on me mentally to the point I just feel sad, overwhelmed, exhausted and sick. I beg my husband to stay home with me every morning before he leaves for work because I panic at the thought of being home alone.

But my little man has been a little more cranky here lately (I think he’s teething) and just the sound of him crying about sends me into a panic. Idk what’s wrong with me! I just feel so alone. I’ve tried to tell my husband how I feel but it’s just so hard to explain. I just don’t have anyone to talk to. I live by my in-laws but I don’t want to ask them for help or tell them how I’m feeling because my mother-in-law and sister-in-law already think I’m a horrible mom because I chose to bottle feed instead of breastfeed and have trash talked me so I’d rather not talk to them.

But I just don’t know what to do.

My husband has been helping with the baby when he gets home from work but I just feel so overwhelmed. I can’t take much more.

I feel so guilty for feeling like this because I love my baby so much.
