I read your worries.
Meditation instruction is Kushikumo's field of expertise, so I'd like to give you some advice.
I usually give guidance while listening to stories one-on-one, but in my experience as a humble monk, it's possible that Noko (while meditating) was particularly “let's relax” and “let's lose strength.” If that is the case, it seems that the opposite causes Noko to break away from her natural body, causes strength and distractions, and confines her free mind in a cage of worry.
So, let me give you one piece of advice.
I want you to observe your breathing a little while meditating. Sit down (whether on the floor or chair) without being too particular about posture or how to sit, then take a short breath. You'll probably want to take a breath after a while, so inhale as you want (either through your nose or mouth is OK). If you inhale then, you'll want to exhale at some timing this time, so then exhale as if you wanted to exhale. Breathe in as you want to inhale and exhale as if you want to exhale. Also, inhale as you want to inhale, and exhale as if you want to exhale... As you exhale, try to feel the area around your chest or stomach. Aren't you naturally losing strength? You may feel like the inside of your body is loosening up.
Actually, that should be the case, and if you don't lose strength in your body in order to exhale, you won't be able to exhale in any way. Therefore, even if you don't try to force yourself to lose strength, your strength will naturally go away. We just need to “feel” it, right?
This is “meditation to observe breathing.”
Please try it out for a bit.
One more remark while being presumptuous. It is said that he has been working on meditation for half a year even though he is suffering, and I think that in itself is a splendid thing. Don't aim to gain anything, smile at your inner changes as they are, and accept them just as they are, as your body (and by extension, life) accepts them as they are, in your instantaneous awareness. There must always be good things ahead of that.
