questions on my meditation practice?
sure here is the way to set the citta into  right samadhi, contrary to whatever wrong samadhi you have developed,
with this sutta https://www.accesstoinsight.org/tipitaka/sn/sn55/sn55.040.than.html, it is first physical seclusion, which means less distraction, fewer objects cognized, then it is mano which has piti and the kaya has passambhati then sukhaṃ vediyati, and the citta has sukhha then samadhi.

the way to get piti with mano is to sort out your Vitakkas with sati, ie satisampajanna, Satipatthana, ie knowing when a Vitakka arises, then judging it as either wholesome or not, and  knowing when it vanishing , and if it is unwholesome dropping it  by thinking of something good [instead of letting the bad thought proliferate] and when you have wholesome thoughts, you get glad to have wholesome thoughts. Same thing with feelings and perceptions.

In other words, when you have good thoughts, you are happy and when you are happy the citta is calm and enters samadhi.

Of course, before that, you must learn what is wholesome and not wholesome, because puthujjanas do not know what is good and what is bad, and buddha explains that here https://www.accesstoinsight.org/tipitaka/mn/mn.009.ntbb.html
