Wow... Sometimes I feel that way too. I feel like no one cares, like everyone hates me, and if they don't then they should...
But, there are people who care, and maybe they just don't understand, and so it seems they don't care, or they get frustrated because they don't understand... It's hard to be a teenager...
I realized though, that when I feel that way, it's my fault I do... No one but me can make that choice, to be happy or sad...
You can't change how hard or steep the trail is, but you can change what you put in your backpack.
I know that knowing this doesn't make the trail any better, but you can put it in your backpack, and it's weightless... All these problems that we choose to hold onto, is just like putting rocks into your backpack, which makes this "backpacking trip" we call life, so much harder.
Make the choice to be happy.
