A sigh escapes even the souls! 
Mufti Muhammad Tasleem ud Din Al-Mahmoodi
Mental stress is a seemingly invisible burden that slowly grips a person's entire being. In the beginning, it comes as just fatigue of thoughts, but then this fatigue descends into the veins of the body, filling the hands and feet with heaviness, the breath with irregularity, and the heart with an unknown fear. A person walks around, but somewhere inside, everything seems to stop.
When thoughts become entangled, words also abandon you. A person wants to say everything, but the tongue becomes mute. Even if there is laughter on the face, the heart feels empty like a deserted room. Nights are spent awake, and days become a burden. In such a situation, even a trivial matter strikes the heart like a wound and settles in the eyes as moisture.
This condition is not just of the body, it is the fatigue of the soul. Those sighs that do not reach the lips, gather in a corner of the heart and break a person from the inside. A person does not consider himself weak, but still, he continues to shatter little by little every day, without any sound, without any witness.
And then a point comes where words end, complaints get tired, and eyes just lower. That door where a person is heard even without saying anything. In the silence of prostration, the burden of the heart begins to lighten, tears themselves become prayers, and the broken inside seems to find support.
Indeed, all these fatigues end by coming to the door of Allah.
