Is it bad that I think I manipulate people into liking me so I feel better about myself?
Why would you manipulate people like that?
To make myself feel better about my life.
Manipulating others into liking you isn't appropriate behavior. When you manipulate someone into liking you, you are establishing a friendship based on lies and not on mutual honesty. You should refrain from manipulating people and try to be honest and forthright in your personal life.
I've never manipulated anyone with bad intentions.
Your intentions don't matter. You're being dishonest with them for your own personal gain with no consideration for how that might hurt or confuse others. Do you see how selfish that is to do?
