Over control and energy dissipation

As a beginner, after 3 months of quiet intensive meditation, i feel exhausted. And I understand that it’s linked to my relation with every type of duty during my life. Studying, working, relations or just simply living, where i feel “ have to do “ emotions, and being extreme with behaviours and self control. So i go out of energy. I really enjoy meditation and i am enthusiastic about it, also as a philosophy, trying to bring it to everyday life. But I feel that i control too much my self, with thoughts and actions, and it’s frustrating a lot. This is not a new thing but, being aware of it now makes it a strong obstacle. I feel a little bit lost. Maybe someone could share some similar experience and to how to deal with it.
