I also lost my mother when I was in my early 50's.....my father about 15 years before that.
Sometimes we do what we have to do & we just put one foot in front of the other & YES, God gives us the strength to do it without totally falling apart.
I know I went through a trauma in my mother's home at the time she was dying.....it took me almost over a year before I could get back in the house & really deal with it because of all the horrible flashbacks I was having & was still struggling with the anorexia that the stress & trauma pushed me into.
Being an only child, I had no one to help me go through it because I was in the middle of a horribly bad marriage at the time...
But I know that sharing things & calling & talking with my mom was something that took a long time to get through.
I'm glad you have your university....please make sure that you hold onto that & continue no matter what.....it can be so difficult....just like dealing with the house to continue pushing on with your life.
Grief takes a long time & there are a lot of different stages that we go through.....please be very kind to yourself also & look into the different phases of grief so that you understand your emotions better.
My heart is with you & so are my prayers
