Help Why am I so naive??

[hanginglights.]

I am so incredibly naive and easy to take advantage of. I was raised as a Jehovah's Witness and was not (am still not) allowed access to the outside world. I went to public school once, and didn't understand why everyone bullied me relentlessly, and took advantage of me. I am such a people pleaser and a doormat or others, I do think it definitely has gotten better since then, (that was 2 years ago now) but at the same time, I am still the same, or at least eerily similar. Why am I such a naive people pleaser??? It makes me so fucking upset. I feel like my past has something to do with it, but I just need some more opinions.. I hate it so much about myself.. makes me wanna die.
