Torah study

I would like to reflect to the Rabbi a certain situation that I am experiencing and would appreciate the advice of the dear Rabbi. Unfortunately, I left the yeshiva after I saw that I was unable to study, I enlisted. My Rosh Yeshiva said that I was destined to be a great Tah Ha-Tah and after the army I would return to study. Now, in my free time in the army, I am unable to concentrate on anything. There is something else that I would like the Rabbi to be aware of. If I could talk to the Rabbi about this issue, I would be very happy. In any case, regarding what the Rabbi said, I have a great desire to be a Tah Ha-Tah and study Torah. But I felt bored in the place where I studied to the point that I was unable to study regularly. Does this mean that there is no option to return? I thought about transferring to Netivot Olam, where the Rabbi studied.
