I am all for sharing about general issues, they do not have to be specific in detail, but it is often the sense of being alone, this is something not common, and I am the most feeble etc. rather than we all have x issue, but this is how I cope.
I will share one that I have learnt about. Anger. In a close relationship, with love, desire, planning etc you easily trip up over each other. The frustration can lead to anger and the anger to words you regret. It becomes a struggle to supress you feeling and always be nice, but it all gets too much sometimes.
So I found I could emotionally divorce myself, walk away, and be alone, really alone. I could let myself go to that place and give up the relationship, just let it go. Part of me would feel guilty and want to stop me. When I was truly there, the emotion had put me where I needed to be. I found there I could learn to love again, to come back, to see what I appreciated not because I was scared of loosing it, but because when alone, it did mean something to me.
It has taken many years to learn emotions are there for a reason and you need to listen. If you are not careful though, anger can go to hate, and hate to worse things.
Now I am not saying the emotions I feel are right, but they are real, and I need to let myself feel them or they do not go away or change.
So that is one of my struggles and my victory.
