Happiness.

If you are one that make other people's happiness a priority that supersedes your own.
Stop, re-evaluate the situation and see if the satisfaction garnered from there eases you. More often than not many shall admit we do things for other people's happiness.
The reasons are endless here...
[ insert yours here]

Personal satisfaction becomes a child in the eye of making sure x and y are happy.  Everything  you do will desire the acknowledgment of another only then at times will you feel the satisfaction . You become dependant on the need to have someone around in order to do something that makes you happy. That honestly ruins you.

True happiness isn't depentent on anyone but you.
You have to dissociate from the requisite of individuals to influence your peace. Love yourself with the love  of a god for their subject.
Live yourself with desperation that drives the force to change.
Perform regular introspections as they keep you aligned with your objectives .
You'll learn to take well care of yourself in those circumstances.
"If you change,  you don't remain the same'.
If you don't change, you remain the same".
