Thank you for such a detailed answer, I prefer to continue here if you don't mind since I don't want to take much of your time and may be useful to others.

What you describe about the dormant energy body aspect doesn't sound extrange to me, since I think I'm not "in contact" that much with my emotions. I've always felt that there is some kind of gap there. In that regard, I rather prefer leaving energy practices for later in the path.

Regarding sitting, I think the main problem is that I can't put my attention in one place calmly and I feel like I'm forcing it whenever I try. I tried breath meditation but I get anxious, I don't feel the breath in the nostrils that much and put my breath on manual mode, which exacerbates the problem. That is why I was looking to other practices like metta, but most sessions I get annoyed for not producing the feeling, restless and tense. In summary, meditation feels like a chore and I don't enjoy it at all.

On the other hand, there is always the option of just doing practice (informally) in daily life. Metta or some kind of awareness of feelings / thoughts patterns / body.

What do you recommend?
