Why do I struggle so much to understand and explain my emotions but I understand well on other's emotions ?

The people who have gone through difficult times i terms of their mental health, may not be able to help themselves, but can understand others much better because its their subconscious that tells them the extremity of mental disorders without anyone to listen or talk to. Yes, I feel the same. At several moments I'm devastated and awful, but then also I come here to listen to those in need, I don't know why, but it makes me feel contented in a way or two that I'm not a useless creature, I can give emotional support to someone in pain! I'm proud to be a listener here. Even though, I might be ultra lonely and terrible, but my subconscious brings me here on a regular basis. And I regret why didn't I get this platform earlier! Really, just chatting helps- the listener me too :) Thanks for reading my thoughts... Hope you all are doing well.
