not coping well with new puppy

i broke down today. as do all people on this forum. for context, i got a 8.5 week old mini dachshund just 3 days ago. he was my dream dog and have been wanting to get a him for over 2 years since i moved to a house, and he is my first puppy.

i just… don’t think i can do it. i sobbed today and have been feeling very regretful with my decision. the anxiety is hitting me hard to where i could barely eat or sleep. it really hit me that i don’t think a puppy is just fit for my life. i’m having an extremely hard time adjusting to a furry friend in my life.

i know i’ve barely been with him but i already miss my old life where i didn’t have to worry about him. i feel absolutely guilty. i don’t know why i’m not as excited or happy as i thought i’d be.

for now, i’m just sticking it out and seeing how this first week goes. i go back to work tomorrow and i’m a bit nervous as to how he’ll react overnight, since i work nightshift. i don’t know. in the mental state that i’m in i don’t feel motivated to train or play with this guy. considering of rehoming if i don’t feel differently. :/
