Sorry for your loss, Flora Faun. May the person (since I don't know man or woman) rest in peace, and may you find gratitude from cherished memories. The person is with you, in your heart, in a special way. Each person has a unique perspective on life.....and when we think of a loss in our life......death of a spouse, partner, family, friend.....even a job, a business, a car, money, clothing, the car keys, a valued possession or something we didn't value because we take for granted.......all these things are practice for the stronger emotions of losing one we love. When we can take time to quiet our mind, we can think about a concept---these all involve change in our lives. Mostly, these are involuntary changes, so our emotions are very natural to be stronger than if they were voluntary, by our choice. Since there is only 1 way past the pain....to go through it.....your support network of friends and/or family (regardless of the number of people) become your biggest asset to lean on in difficult times. There is NO timetable to feel filled with vitality as before the loss........but YES you will have that full vitality return to you....someday. And, there will be good days & bad days in between. Simply provide your own inner love....accept yourself as good....and notice more good in others (be patient because they may say things to move you quicker because THEY are uncomfortable with your pain).
That all said, it's absolutely, perfectly natural to fee empty....maybe a little numb.....and be aware its OK. AVOID drugs or getting drunk during this time to allow for the best trajectory towards good health, and balanced emotion. Find a professional support group also, who can help you locate workshops or professional colleagues to help you with your loss.......and that it is OK to laugh with pleasant memories, and seek exercise and physical comfort through your body's natural sexuality.
Remember....there is no such thing as "closure"....it's a myth. You WILL feel vitality again, like when we go to the gym to lift weight....soon the burden isn't as heavy. Runners that couldn't do 1/2 mile soon adapt to do 10, 15 miles. Private message me if you want any resourceful information.
Best in support to you!
