Welcome! I know almost exactly what you're going through. I just got married and my SS15 and SD19 are estranged from their mother and live with us full time. My BS13 and BS16 are here 60% of the time. I can't explain why, but going from single mom with two kids part time to mom of a family of six (4 teens!!) has been overwhelming. The kids are sweet, but total slobs (mine aren't much better). Every time I grocery shop, it's like plague of locusts come through. I became very resentful. Had a lot of arguments with DH. Cried and fumed a lot. Felt overworked and underappreciated. To add to the drama, our therapist is out for two months, we have a new puppy and we are down to one car. I've spent entire days running his kids around. Plus I work, too.

I've had to really practice not sweating the small stuff. They're teenagers. If they want to live in squalor, keep their doors closed. I hired a cleaning service for the first time. I joined Costco and buy enough for an army. Cocktail hour starts a little earlier ;). I'm adjusting, slowly but surely and you will, too! Count your blessings - we could have all this and still have a-hole stepkids who hate us, like many on this sub. Chin up, you're not alone!
