I hope you are still here.
I told you what works sometimes for me.
I try to be more logical than emotional in these moments.
Sure this is not your fault if those people you said were not .
And first of all dont press yourself to not blame yourself , if you do you it make it worse so its okay to feel quilty .
When you are sad you have to express somehow this sadness even if you are alone , even if you cry outdoors .
And really you are not worthless , this is something another people said to you not you.
