I have been where you are and still am grieving. I don’t think words can ever describe the hell of seeing your children, especially so quickly, with another woman.
i too have had therapy for over a year. Yes it helps. But you are still stuck with this horrific situation. People will give you good advice, shrinks, therapists etc. But it is not a cure like a physical ailment. I am always told to sit with your emotions. Well, sure you know how that feels.
Life totally sucks, you start to heal, but it is not linear. It is a total roller coaster.
You can find hobbies etc but it does not stop the grief. The loss is 50% of kids, or whatever arrangement, is still a tragic loss.
You can only walk through it and endure the pain. It is such a horrendous journey.
But out of the ashes, hope will arise, and one day you will see beauty.
Some mentioned Tracey’s book, leave a cheater gain a life. Such a great source of healing and laughter.
Blessings.
