You think you have the answers

I have spent a great amount of time lately being told things like "If you are grateful for the things you have then you will be happy" or "What reasons do you really have to be so unhappy" or "I would trade places with you in a second". It is funny how people always say things like that, they know that is is impossible to trade places with me, therefore they feel justified in patronising me with that ridiculous statement.

I am not asking them "Why aren't I happy?", matter of fact I don't actually remember asking for there opinion on anything, cause no matter the situation I could never possibly be as worse off as them. I have given up asking for help, what is the point? I am never told anything constructive, only that things could be worse. I realise that that statement is true things could be worse, even when asked I can never fully describe why I am so unhappy, I just am.
