I'm sorry you're feeling this way. It must be a terrible feeling.

If I may, how do you know it's a one-way situation? Are you sure you aren't helping people in some important but less-obvious ways?

Do you ever volunteer, donate to charities, speak kind words, comfort someone who's hurting, plant flowers, help someone move, leave a big tip in a restaurant, vote, do a favor? Those things matter, and they add up.

And frankly, if you're not doing those kind of things -- start.
