Thank you Hypershadows for being open to work with me and for your patience with me.
Writing till 1am shows your commitmment to yourself to hopefully tide through this ebb of emotions and thoughts rushing. Like seawaves, let us watch them as they ebb away.
On your apology for using, “I think” and mis rememebering as well as being critical to yourself as being right…
It does sound no apology is needed, even with your terms. 
You are right to think. You have every right on what to think about too.
You are right to think undesirables and then acknowledge them and decide what to do with these thoughts.
Same for thinking about past and acknowledge them as well.
Why did I use the word “acknowledge”?
When we carry school bags on our shoulders, we feel the tugging and weight on our shoulders.
When these thoughts pass our minds, I quote,
“I think mostly the brain and the chest I suppose. Feels a little heavy and sunk a little”
You acknowledged those thoughts because the weight is heavy and sunk in a little.
Now it is right to only do service to yourself to carry as much weight you may bear, just like how we pack our bags enough for the day’s schedule.
Does this mean you may choose which thoughts to carry with you that can be useful to you?
Or carry everything and decide when the moment comes?
How much may you carry to do a normal walk?
How much may you carry so that you dont feel those weight?
What kind of thoughts don’t weigh on you?
What kind if thoughts weigh on you?
Now that we are done with thoughts. Same for feelings for the above questions. It may show some clarity why those feelings come and go. When the feelings go, do you let them go or do they go away?
I am heartened that you mediate yourself from physical noises and distractions by going walks, drawing boundaries to surround yourself with music, me time looking out at the sky. Try take slow breaths with slower music? We could do those as 10 mins exercises.
Only you own this 10 mins for yourself.
Hang out with people to get different perspectives too. Like how we are chatting! It can be anything from trivial to focused things.
Cheers and wishing you a smooth transition till a good break at CNY.
Good health, eat and sleep well, my friend.
