Anxiety Support Group
Anxiety is a physical condition marked by intense and persistent feelings of distress, fear, angst or dread. General anxiety caused by routine day-to-day stresses usually passes quickly and is experienced by almost everyone at one time or another. However, such feelings that linger over time and are very difficult to cope with, and which lack a clear cause, may indicate...

I don't think about getting "over" things, but more about finding ways to work around them. The thing happened, I can't change it, but I don't have to always sit there staring at it. Nor do I have to force myself to never look at it. Balance.
It's going to be there if I look or not. So when I find myself really really sad, I'll make a deal to look away for 2 minutes. Then check back...yup still there...didn't get worse, didn't get better. Then look away for another 2 minutes. Sort of becomes a habit. Eventually I can get where I check in once a day.
That's just what works for me.
Best of luck figuring out what works for you,

And, slamming the door is understanding that you are still in grieving for your loss with the wife leaving "without warning" and your dad "horrible dying pain". Those happened, what you can change is how you react to your thought process in coping with both events. I suspect that as you find your new balance, you will learn the little pieces that were clues as to your wife's changing attitude, feelings, and acceptance of marriage rules. When we first get notice that change happens, we have to accept our feelings are valid, and that as we change, those feelings will become part of our change. It's up to us how we use those feelings to improve our well-being.
When a parent dies, and "horrible pain" is part of the natural process of the circle of life, it becomes necessary to add pleasant moments when we process the pain of the ending.
You are not alone, and know that you're stronger than you realize.
Have you ever heard of the serenity prayer?
God grant me the serenity
to accept the things I cannot change;
courage to change the things I can;
and wisdom to know the difference.
Living one day at a time;
Enjoying one moment at a time;
Accepting hardships as the pathway to peace;
Taking, as He did, this sinful world
as it is, not as I would have it;
Trusting that He will make all things right
if I surrender to His Will;
That I may be reasonably happy in this life
and supremely happy with Him
Forever in the next.
Amen.
Regardless of your religious beliefs there are some great nuggets of wisdom there. I can’t change the way my parents died, I can’t change the fact my wife left me or cheated on me, I can’t change any outcome, I can attempt to influence a situation unfolding in front of me, but outside of that, I am powerless as whatever tragedy develops before my eyes! If you are religious, talk to your pastor, get involved in your belief! If not, find support in therapy, your friends, family, and work towards finding true closure, the state of being where the event(s) no longer has the power to set you back or send you into a depressive state! You can do it, there are better things ahead and you’re important to us!
