Am.I overreacting?

I called my boyfriend today because I've been stressed out with my son he's 1 he's getting 4 teeth so he's super clingy & if I walk away for a second he freaks out. So I called him to talk to him & he wasn't being rude or anything but I had a little attitude because he kept asking if I tried doing this to calm him down if I looked it up just kept question me so I got upset. But I ignored it as usual and let him finish saying whatever he said the I asked if I can drop him off.In the morning because my son has his doctors appointment tomorrow we have another car it just has no ac and it over heats sometimes and he got upset saying I dont need it cause the appointment is in the morning so it won't be hot and I only need it for the doctors. I got over it it just seems every time im stressed and I try and talk to him.About it it turns into a situation about him
