Welcome to the forum, lodonyo!
I am sorry to hear about your situation. I hope you two will find a solution.
Regarding your comment, “Venerable Walasmulle Thero and the absolution movement of sri-lanka describe “emptiness” with the example of the 3 children and mother. Child A, B, C ..”: If you post a link to that audio or video, I can take a look.
– Normally, Ven. Abhaya is very good in explaining concepts. It is likely that you misunderstood. Can you understand Sinhala? Ven. Abhaya explains mostly in Sinhala.
Regarding meditation, you said: ” I have enough practice to be aware and catch my subconscious motions.”
One is not aware of subconscious or even initial mano sankhara when they first arise. Only when one starts generating vaci sankhara (talking to oneself), that one becomes aware of the thoughts and that is when one CAN stop any bad thoughts; see, “Correct Meaning of Vacī Sankhāra“.
The best way to improve meditation is to first understand the goals: “Bhāvanā (Meditation)“.
I do not know anything about your meditation experience. If you can read a few of the posts in that section and comment, may be we can make some suggestions.
