overwhelmed

Can someone please tell me if I'm wrong: my fiancé, our son, and I just recently moved to Washington from Arizona. Arizona is both of our homes and we left all of our family. A day (literally like 12 hours) before I left to my new home I found out my mom has leukemia. I have nobody in Washington. I am a stay at home mom so I stay home all day with my son while my fiancé works literally the entire day. I feel extremely lonely, sad, frustrated, missing my family and mom, and annoyed because I can never ever catch a break or get a breather. I feel so turned off by my fiancé I think maybe because I have so much going on in my life plus I'm alone ALL day. I'm starting to think that his job and career isn't one that I want to last forever with....he is usually gonna sun up to sun down lately and I'm just so homesick...Overreacting or do I have a reason to feel like this?
