So true what you have written, when we expect something from others and we don't receive it, especially if you have done everything for them, yes your feelings can be hurt.
I suffered with those feelings for many years. Until I realized, as you have wisely written, that I had to work on myself.
If I believed in myself knowing that I have value to this world, NOTHING on NO ONE should rob me of my inner peace and joy!

Thanks for your words of wisdom @sauravrungta!
