Life itself stressful. Our brain... the mind is just filled with a lot and our surroundings too also affect us.

Staying in a place where there's lot of noise as someone who doesn't appreciate noisy environment but yet you can't leave because of finances is super stressful. You just have to deal with!

However, the body and mind can be broken without indicating that it requires repair.

True. That is why we shouldn't take any symptoms lightly especially when we have health issues like hbp, ulcer etc.
