It does get easier.
It is also my personal experience that whenever I am going through a time of grief, if I have areas of other types of grief or pain in my life that I have not dealt with or acknowledged, that the "current" grief will be deeper and last longer.
Just my own experience over the past few years and a number of losses.
Give yourself a lot of grace, and get whatever support you need. I have found support for my grieving processes in groups, with a counselor, and with friends. It gets better. Give yourself plenty of time.
