IMO, part of the difficulty with grieving the loss of your marriage, best friend, half your financials, what have you is that in the case of MLC, the rest of the norm look at it as "just a divorce". When did getting a divorce become not a big deal? And yet, that seems to be the case.
With alzheimer's, alcoholism, any mental illness, othet people have sympathy or empathy. It's why we flock here, imo. Grieving can be done on one's own, but grieving with the validation of someone who gets WHY you are grieving quickens the grieving process. If you burst out crying over your situation in a group of friends, and everyone around you looks like you have lost your mind, do you feel your grief had been acknowledged or judged? And if judged, then do you have a right to grieve? And if you have no right to grieve, how will it ever get processed?
So often, we (the generic we) justify that our loss is not so bad, it could have been worse, blah,blah,blah. We've either been conditioned to suck it up and trudge on through, or to minimize our own feelings. For some of us, we go through life like emotional zombies. We know we feel bad, feel a loss, but maybe it's kind of a familiar feeling. Do we grieve something that seems so familiar? Do we grieve that we have no feeling to grieve if that should end up the case? Do we grieve that we don't have the emotional intelligence to know we were supposed to grieve? It piles on at times, so much so that a person might become numb and be unable to grieve at that time, even if loss is recognized.
So many losses are intangible. The feeling of safety. Knowing someone has your back. The expectation of a "How's your day going?" text. Looking at relationships differently. The fact that you can no longer retire. Trying to identify them is often like grasping at will-o the wisps.
Life, the world and everything is messy. If only 42 could be the answer.
