I cant help seeking external validation

So i was raised on emotional crumbs.

How people close to me would describe me : emotionally stable, mature, thoughtful, ubshakable.

The core issue : I cant stop seeking external validation. For example :

(All of this goes on subconsciously. It has taken me years to get to this realisation)

1.if others say that yeah my situation is fucked up only then i fully allow myself to accept it. 2.i always look for approval 3.i am unsure of my decisions regarding myself. I make great decisions for others without second thoughts. 4.Although i have alot to feel worthy i still dont feel that way. 5. Even the smallest of good gestures from people seem earthmoving to me. Whereas i am available for people at my own cost.

All of this probably stems from lack of self esteem.

How to build it. I have substance to prove myself but i still cant do it. artificial int. told me to

1.count daily wins 2. Visualize and heal my younger self who needed it.

I need your opinions guys. This has kept me stuck in multiple departments of my life.
