I was going to get a puppy this weekend but now I’m getting scared and depressed.. *read*

So I’m getting my German shepherd pup this weekend and I been so excited about it and was so ready for the experience

I have a 2 & 4 year old and they loooove the puppy.

I suffer from depression & anxiety, and idk if I’m getting cold feet but I’m getting second thoughts for random reasons

I’m just getting depressed and worried, I’m not sure how life will be with a dog in general, idk if it’s a big life change like having a child, idk

I don’t know what to think, I don’t know if I’m overthinking and this is natural.. idk if it’s just my depression kicking in, I just don’t know

I wanted this puppy sooooo bad but now I’m terrified! I just need to hear what you guys have to say

Edit: the puppy currently is near a 5 year old & 5 month old, the lady said the dog is really good with them, she’s also trained the puppy to be crate trained & taught it basic demands like to sit, she just hasn’t potty trained him just yet..

I’m just scared to changes, will this be hectic? Or a huge change? I don’t know..
