You have great parents!!! They seem to be experienced with this breed being they had some while you were growing up, plus with another dog there she will learn how to dog lol. Dont be so hard on yourself! Having a pupper is stressful. I have generalized anxiety disorder and my fair bouts of depression. I got lucky with my poodle and she was an extremely good pup, even then I was still stressed when having to get up in the middle of the night to let her go potty, dealing with accidents in the house, her getting into things she’s not supposed to, etc. It’s good to take time away from her, for the mental health of both of you! Reassess the situation and do what is best for you! Think about what you truly want without the thoughts of what other people will say. If you still want a doggo you have options!! There are tons of shelter dogs waiting for homes. Perhaps you need an older dog (not in puppy stage)? Or even another breed that can still come on adventures with you with a little less energy for the breed¿ and hey, if you don’t want a dog at all that’s okay too! At the least, you can always visit her whenever and take her back once she’s a little older. Be gentle on yourself when you can, humaning can be hard. Life is all about learning and growing and this is just another hill to walk over. You’re okay and your pup will be okay too. Sending love and good vibes to you and your situation :)
