It's good and healthy to discuss our own troubles with people close to us, our family and those ones that we call friends. Nonetheless, the sensibility is required to find suitable moments and ways to do so, in order not to become peevish. Yet, many people just wouldn't care, throwing up to you all their "sicknesses" at the first available opportunity. Failure in interfacing with people that care about you results in becoming isolated, damaging oneself on the first place.
It looks something so obvious, yet a number of people make this error and either do not realise it or confuse it with being honest and open. Good luck to them.
