I think my dog loves me too much?

My sisters friend who has a Chihuahua had puppies and I picked mine out and when we went over there I would always get that one. Her name is Martini. And I got her when she was only 3 days away from being 5 weeks old. And I knew that it was too early to get her but, the woman said since they were eating dog food that they were good to go. But I knew it was wrong & they needed to stay longer but she brought to me which she lives 20 min away from me. And at first when I got her she wouldn't even eat the soft dog food. When she would at the ladies house is what she said. So I had to bottle feed her from this powder formula I got at the vet. I was going to train her to sleep in the kennel but, she would wine all the time to get out. So I finally let her sleep with me. She had every night since. She would always sleep like right on me. When she got older about 2 months she would wine for me when I left the room like literally wine so loud because she couldn't get out of the baby gate I had put up so she couldn't get out. She followed me everywhere. Now she is 7 months old. She never wines anymore when I leave. But she did wine at the vet when they took her in the back when she was sick. Now, whenever I go in my room she crawls under my door. When I leave she leaves.. I have a space under my door she crawls through. She will lay on her side and push herself under. She will not sleep in her bed. I make her get in her bed when I go to sleep but when I wake up in the morning she is in my bed. She always tries to run out the door when I leave.. And when I do get home she is so hyper for like 15 minutes and she jumps all over me. She will growl when other dogs try to get in my lap. When me and my cousin were play fighting she was trying to bite her. She isn't even a mean dog. Shes never bitten anyone or another dog. And I have to admit I do love this dog. And I do like knowing that she sleeps with me because I dont know it just seems weird when she isnt because im always thinking that she is going to get out the door and runaway or, her and my sisters dog will get into a fight because my sisters dog is very mean and will try to attack her. How do I get her to stop following me around? And to sleep in a kennel without yapping to get out? I feel bad when she whines. I just feel like, example.. When your little sister follows you around and does what you do and tries to copycat everything you do to the point of where its annoying.. But its a dog. Get it?
