When you feel it's just you against the world, it's very depressing.
When you are always made the frontline in making decisions and taking the blame and stepping up and acting first in situations, it's hard. It's very tiresome. It drains whatever positive spirit you have left in you.
It's okay to do those things as long as it's not expected of you ALWAYS.
Sometimes you need someone else to do the talking, planning, decision-making, shielding and protecting.
And when there's noone, that is when you feel very, very alone.
