Ranting about puppy blues

Hello! It's been a week since we got our 2 month old lagotto romagnolo. I've read a lot about puppy blues and I know it's natural and okay to feel this way. Before saying more, I also wanr to make it clear that I am a high school student, I turned 18 last month and still, obviously, live with my parents. So, we got our lagotto, Archie, last week as 'a birthday gift for me', and my mental health went downhill after that. I am so grateful that everyone is spending time with him and not just me because I think I'd lose my mind. I feel anxious, stressed and cried once (and he comforted me when that happened which was so sweet). I am more anxious about what might come in the future. So far, he has been good when left home alone – we leave him downstairs in the living room and he pretty much naps. He has been playful, hes learning commands such as sit, lie down and stuff, and he sleeps so good at night. Hes not fully crate trained – last night he slept so nicely in his open crate, but hes not used to it being closed yet and my parents discourage the idea of it because they see no point in him being closed when hes not home alone. I've been reading so many subreddits about how naughty he might get. I'm terrified that he'll become restless at night (because he sleeps in my bedroom) and I'm wondering if I'd be happier if he didnt join our family. I've been so unmotivated to do things I enjoy despite him being so good so far and despite not being the only one caring for him. I know this is all temporary and will pass soon, which I'm so excited for, I just really needed an outlet and hopefully to read some of other's experiences. Thank you for reading!
