Unhappy Please help, new puppy!!

I am one very confused and upset new time dog owner to a Labrador X 14 week old puppy. We have 3 young children (10,6 &3) who have always been a bit jumpy round dogs and so didn't force dogs on them. We talked at some length about getting a puppy of our own that we could train and incorporate into our busy family. I was looking one day and found Rocky, local to us and at 10 weeks old in need of a home as owners circumstances changed and they could no longer look after him. I am home at the moment but do plan on going back to work next year so thought I could be around. Also, Rocky's birth date is the same as my eldest daughter so was immediately suckered in!!

I talked it over with my family and we met Rocky, a lovely little black pup. Yes, we will take him!! Collect on Monday by Wednesday doubts began to trickle in. My children were a bit nervous around him as he jumped up and playfully nipped and even though a pup quite big against my 3 year old! I played with him and thought he was great despite the nipping, pooing and weeing, which was cracked quite quickly. However, the tables have now turned, the children and husband are bonding but unfortunately the initial desire for Rocky has worn off for me and now I'm left in a terrible dilemma! It is very stressful in my house with three boisterous, lively children all demanding my attention as they do and I'm afraid that Rocky may have been the straw that broke the camel's (or my) back I have become extremely emotional, feelings of complete despair and isolation at the prospect of having another body being dependent on me. Life was good before and I had things sorted, time to myself and then I got Rocky. Never having had a dog before ever it has proven to be one of the most testing times of my life and unfortunately has triggered a state of depression where I'm constantly crying and wanting to turn back the clock. I'm now under the doctor and on antidepressants. Rocky is a good boy, learning everyday,behaving well and attending puppy school, it's just me! I'm on the verge of a nervous breakdown but wish no harm to the dog. I want him to be loved and part of a loving family which is why I'm finding the decision of whether to keep him or rehome him. I knew it would be hard, especially with a puppy, friends with dogs have been very sympathetic, but if I'd of known how hard and how I would be feeling now I probably would not have got him. The sad thing is we have only had him for 3 weeks but they have been the worst of my life. As I'm at home I would be the primary carer. If anyone can offer advice it would be really and truly appreciated, thank you.
