It is so, so, painful sweetie,, vent, scream and cry! ( my tears dried out for awhile too and then I just felt this dull ache in my chest and when I finally cried it eased that pressure!) Mourn your loss ....this change will not come overnite,, you are right!
NO~ you cannot erase 20 years in weeks. I used to say this all the time! And mine was only 10! So this qwill take time,,, baby steps,, or even crawling like I used to feel like I could only do. I did not eat either. IT surely is an indesrcibable pain but as you focus on you day by day it will help you. I worked hard on detaching and still had emotions we are afterall only human. GIVE yourself time honey...
God bless, ALI
