I am so sorry you were afraid to post this. You sound like the type of caring, thoughtful person YT needs more of. If you ever decide on another puppy hopefully you'll use all you've learned here to make a more informed decision.
Many, many members have been in your situation. We always advise them against bringing home puppies so young because that's what's best for the puppies. Once the puppy is in their new home however, we still want what's best for them - and that means being here to support you, to share experiences and offer advice.
I am not advocating that you bring this puppy home so young, but if you choose to do so then I will be happy offer all the help I can.
Bonny
