Some people will always try to make you feel guilty about something.
And this can be hard to take, even worse if you already feel bad over the pasticular thing that they are talking about.
It can be anything that you should have done but just haven been able to do yet.

But do you know what?
You are the one in charge here, you are the one that has to do it obviously so tell them that.
They have no right complaining about what you do or dont do,
since its your life and you who will have to live withnot accomplish whatever it might be.
