I was always like this, tied myself in knots trying to please. Got used and bullied.
Its all about esteem, build your self esteem up to normal levels. You are important, special and unique. When you truely believe this, the need to please excessively disappears. And ironically more people like you. Value yourself and others will get those vibes & value you too.
Walk tall. Look the world in the eye.
You are enough. You are always enough.
