No seriously PBB you should just do it, and then blame it on Ozzy.
Remember, it's what I'd do.
Are you saying that people have no choice whether or not they take something personally, and further still have no choice about how they're going to react to it? What's the state of mind of someone who insults someone else on purpose? Someone who's centered and at peace with themselves isn't likely to go around insulting others. So it's not a bad idea to view any insult towards yourself as some kind of blowoff from some other problem completely unrelated to you. And how can you get upset at that?
Butterfly Boy, you need to remember that we only read the sentences you wrote, from our own point of view. And for most of us, those sentences raised a few 'red flags'. We don't know you, you didn't give any background, so don't take offence if people say "hang on, something's not quite right here".
If we had the chance to speak to you in person, you'd probably hear a note of concern in our voices, which is care, not judgement.
Remember your parents love you and want the best for you. If they are concerned about what you are doing, such as trying to make you eat more, you might want to consider why they are this way. You've mentioned 'fat burning' and 'underweight' in the same sentence, and while obviously you want to gain lean muscle not fat, it's normal and healthy for a youngster to have a little bodyfat. I'm not talking blubber here of course. But just be careful, yeah?
There's been some good advice on the thread, so do give it some consideration.
