My doctor:(

So before I got pregnant I saw my doctor Dr. Nigh. I loved her she was so amazing. Made me feel super comfortable especially since I was in my teens I needed info and she was the one. Fast forward to my 20's and in pregnant. She has been my baby doctor for well into 6 month now.  Well she finished her residency and she let me know she was leaving and she thought it wS best to pick another doctor before she left that way I had time to get to know them and pick before she left. Ugh! I was so comfortable with her:( so the next few weeks I go into L&D cause I wasn't feeling baby and while there I met a very sweet and amazingly awesome doctor Dr. Little. She was so incredible. I remember leaving that day telling my husband how much I liked her. Well time to pick a new doctor and well il be she is one if my choices!!! I choose her no questions asked. I loved her!!! She treats me the rest of pregnancy, she delivers Eden and now I'm so comfortable with her I'm like attached I want no one but her. After Eden is born she treats Eden and Eden becomes her patient as well. Ok well idk what happened but recently I've tried to schedule appointment and she is never available!! Is it me? Does she not like me? My son at 9 months got an intussusception and needed immediate surgery. The night before I noticed Eden was not responsive and just sleeping and squirming in pain. I knew something was wrong for sure so I called her and she never responded. I thought it was the flu or something so 12 hours later I took him in and I was devasted. I was so angry!!! If only she should have called me back I would've gotten him in sooner. Eden is now better and come to find out the reason why she never called me back was because she was on leave cause she is pregnant and having complications. Il admit I felt like crap. I saw her a few weeks after the whole surgery and she acts so awkward around me. I haven't seen her as my doctor cause she is never available in like 4 months. I'm so upset. What is going on. I'm so confused and I'm literally seeing a different doctor each time I go in whether for me or Eden. I hate it. What should I do. ? Sorry this is so long but I wanted you guys to understand the whole situation. I grew dependent on her and I'm only comfortable with her and she doesn't want to see me anymore. She is in her last trimester too. Can this be why?:(
