For people which are suffering through bad days, feeling down or, being that honest, suffer of depression:
this might will help understand your problem or other(s) problem better.
Its not fun to be missunderstood on this world nor is it fun if you dont see really any alternative in your life anymore. what ever the reason is why you feel the way you do, remember one tiny thing:
You are not alone.
Suffering of the "black dog" or depression, so to speak, is not good and even i suffer through it. I am on the way to work on it, getting people which try to help me with my problems and i got myself some books which are called "i had a black dog" and "living with a black dog". One of the books, the first, is for people which have depression - the other is for understanding how depression "works".
i found myself the said books as actual videos which are quite nice to look. i hope those might will cheer you a bit up or, at least, help you understand the black dog a bit better.
Depression is from case to case different. Some people might dont understand it and try only their best to help which, for the people which DO suffer through it, might take different. Even if said person might be grumpy, im sure they dont often mean it this way.
i hope this 2 videos/books help you understand a bit more of the world from people which suffer of the black dog...
