1st appointment in one week + lost my "best friend"

Ashley • my fiancé and I just found out we are unexpectedly expecting our first !! Over the moon excited for this miracle ✨
I just can't tell what her problem is. 
Gradually, she has said and done more and more hurtful things, less supportive things, and simply, less best friend things even more so now that we are pregnant. When I told her our news her first words literally were "omg, I'm in shock- my boyfriend is gonna die because now I'm  going to want one." I received a text after I saw her for the first time since our BFP and it said, "I'm literally still in shock you're growing a baby. Like you look normal now, but in a few months Boom, you're gonna be sooooooo fat." I know she is several years younger then me, but I didn't think this person who I have unconditionally loved like family (she moved to CA from Texas for school and doesn't haven't any friends or family here) would ever push me away with such obscene and  non compassionate comments. we met at our college and even though our age difference has shown  through at times, I always gave her the benefit of the doubt. 
I have been experiencing severe morning sickness all week and was at urgent care. She knew this and instead of texting any kind words she asked if I could drive an hour to where she lives in Los Angeles to bring her a cookbook she left at my house. She I told her no way I'm at urgent care and dealing with possibly HG, she said "lameeeee" 
So next, I brought my hurt feelings to her attention and she actually told me "I want people in my life that don't bicker. You're bickering." I was in shock I didn't hear "I'm sorry you feel this way, this is a misunderstanding.. Bla bla " 
I'm so hurt but curious if I'm being too sensitive or over reacting ? Prior to TTC, she only started contacting me if she needed help with school projects or advice with her boyfriend. 
I'm also realizing this is the best time to lose the disingenuine people in our lives. I finally felt better tonight as I lay in bed with my fiancé.   Still hurt but remembering to focus on the positive right now. 
<<< one more week + we get to see our lil beb for the very first time. words simply aren't enough to explain this amount of genuine joyfulness. tonight as my beb gave sweet sweet kisses to my tummy, a calm gently swept me up and away; it felt like golden rays of sunshine, blankets of rich velvet + warm rain. every single thing in my life has brought me to that very moment, to this true kind of love + the unmistakable fact that it's all finally worth it.>>>  xx  ☯
