Hi @wolfofnostreet. This is just my opinion tho. The 'Move on and suck it up'-technique is good short-term, but not so much in the long run.
It may help us by us not creating a scene - as many others are willing to do a lot to avoid the entire spectre of feelings from their conversation partner (us) as they too are or have been feeling the same but have not yet learned how to cope with it all, or maybe they too were raised with the 'Move on and suck it up'-technique - maybe of the same reasons ans the ones mentioned above.
But in the long term, it might have some not-so-much positive consequences. All of our feelings are there for a reason. We shouldn't choose some feelings over others, as they are more comfortable, but rather acknowledge and feel them all. Are you sad? Be sad for a while. Are you angry? Be angry for a while. Denying these feelings is kind of to repress them. And anything repressed, comes back tenfold.
Dealing with whatever is going on, accepting and acknowledging the entire spectre of feelings, asking yourself is there anything I can do about this now, and if so - what can be done, I believe is beneficial in the long run. Be in it and feel it. Process it. Then step out of it and move on. That's what I've learned, and so this is my opinion. I might be way off, but this has truely worked for me.
I hope that you'll feel better soon :)
