Overwhelmed

Hello, I’m currently 34 weeks pregnant with my second baby.. my first is currently 20 months old (soon 21 months).. he still wakes up at nigh at least 1-2 times but can sometimes be more (teething)… plus being pregnant I really don’t sleep well at all and also wake up for no reason… I feel very overwhelmed, exhausted, overstimulated… I feel like I have little to no patience… I overall feel like a bad mom.. I feel like I should be doing more.. more activities with him… play more with him.. idk if it’s the hormones but I just need to rant about how I was feeling… I literally cried for 20 minutes because it’s his nap time and he just refused to go down and I really need a nap… is something wrong with me
