"Dear future me"

I sure hope you feel more assured than I am now. Being 17 makes me feel uneasy, because I can get so confused and irritated with myself that I scream "get a grip!!!!" on the inside very often. I get it, this is when you're supposed to search for your own identity and such, but how long will it take? I still feel so emotionally unstable.
I hope you're much happier than I am now. Have you finally learnt how not to let loneliness get the better of you? Can you feel validated by yourself and not rely on someone else to be happy? If you have actually found someone special, I hope he's not the only thing that has filled the emptiness in your being. I'd be anticipating the first meeting, but it'd be nice if a romantic relationship isn't the only thing fuelling my happiness. I want to feel like I am capable of maintaining healthy relationships and achieving great things on my own, and this person is just going to make me believe in myself so much more.
I wonder how different you are from who I am now. The way I treat the people around me can change a lot in a matter of days. What will a few years do to me then? In the past few days, I've had a lot of people tell me how "young" I am, at 17, and I become skeptical - like is being 18 really a whole different ball game?? Will the important questions I have now be insignificant in a couple of years??
I guess the one thing that's been lurking around in my mind lately is that sometimes, we meet people that we find to be very similar to ourselves. They like and dislike the exact same things as we do and they have the same thoughts and beliefs as we do too. How many of these people do we meet in a lifetime anyway? Does this immediate connection we have with them last then? I feel like I've let a lot of these people go because I take things too seriously, or because we are just not fated enough.

Well, do you still believe in fate? I hope you do. Even though sometimes I think that fate is a stupid concept and gives you a lot of false hope, I still want to have faith in fate. I want to believe that there is someone for everyone who can bring happiness amidst the pain and can change the way you view the world. This person will be bring you back to where you need to be when you are lost and astray and will learn to know you like the back of his/her hand. To think that we will meet this person one day is pretty amazing.
