Drugs are bad. Cocaine especially. Its almost as bad as heroine if not just as bad. Gerard Way figured this out on his own, but it was a little to late when he did. He was already hooked and he knew that his life was on a downward spiral in the absolute wrong direction.
Its also very bad to love someone of the same gender well at least in his parents eyes. Its very very very wrong when said person is your brother.
And its when that brother figures out your drug habbits and dirty secrets that it all comes crashing down.
And Gerard Way knows this.
