Let me tell you, joining the Air Force is the smartest decision I have ever made in my entire life. I'm 19 and have only been enlisted about 9 months, but I love it so far. So many opportunities. It teaches you disapline and they provide the training needed for success. College isn't for everyone right away. I certainly was not ready for it (lazy). But with the GI bill and other benefits like tutition assistance, I will get the chance to have a degree at the end of my 6 year contract basically for free.

I'm an Air Traffic Controller. If you want a hard job, that'll challenge and reward you greatly, i HIGHLY recommend trying to get Air Traffic. It's amazing.

Don't give up! Everybody feels the way you do at some point in their life.
Definitely go to college.

Also, do you think there is a reason why your friends and cousin don't want to talk to you?

Another thing:

IF YOU DON´T BELIEVE that any one will miss you if you are gone, THAT IS THE REASON to stay. Stay and make your mark in this world.
Fight, till you look at life and say: I have done it all, I gave my best, through hell and high water I´ve been, and I saw the day that came after every dark night.
Only time that going away is right is when there is nothing else to be done. When you helped the people who needed, and not when you were the one needing help.

Life it ain´t easy, but until you realize how special and worthy life is, you just haven´t lived enough yet. and you will, girls will come and go, friends too, jobs too, good days and bad days.
Savor every minute, cry when you feel like it, but learn about the time to dry your eyes, become your own father.
It will work out, you will see. Stay and you will see.

Like Goatseye and ps3-sales! I also think the military potentinally is a very good way for you. You never question wether to get up in the morning and if you're unsure what to do, you're certainly told! ;) I don't know how long the waiting time is for the military in the US though.

Between my time in the military and my time at the university (I'm aware that college is more socialized) I definitely enjoyed the army and fellow privates the most. At the university (and college) there's so many academic expectations to live up to whereas the military life with all its physically hard work is just revitalizing.

Many of your fellow privates become friends for life.

You will definitely learn how to make decisions if you correctly cope with military lifestyle.

Also you will gain a new family that will want to succeed because you are an important part of a group that has to be functional.

I felt the same way when I started college, my parents broke up, my best friend moved to australia, I hated my mother and never talked to her for 3 years, my father worked so hard that I only stayed with him once a month. 2 of my birthdays I was completely alone and no one remember them, it was pretty bad.

I felt lonely but with a lot of hope for everything to get better, on college I made 2 good friends and a girlfriend, and I'm very bad doing friends and never had a girlfriend before. I'm just graduated from Medicine school.

My advice is to join something, collage, Air force(like someone suggested), a club(i'm an karate student), a job you really like(hard to find but not impossible), do things you always wanted to(scuba, fishing, painting, learn to play music, climb a mountain its awesome, learn cooking, other language, etc), with someone if possible. Forgive your father, cousin, or anyone that made you feel bad, its better for the long run, otherwise you will feel bad everytime you meet or mention/remember them again. Talk to your father when you have problems or when you're feeling lonely, I'm sure he will try to do something(It happened to me with my mom)

Best of luck, you have a good chance to do great things to your life, make it happen.

1) Believe in yourself
2) Don't listen to losers in your life (That is anyone that says they are your friend or family but doesn't listen to you)
3) Work on being successful in life, school, and work

The rest comes with time, patience, and faith in yourself. For some this is the day they are born, for others it can take decades.

Don't give up on life because nobody cares about you, find people that will care about you. College is a good place to start, make sure to live on campus so you can be more active in college life. Join clubs, form a study group, it's much easier to make friends in College then it is in high school. You have to realize that the majority of people in college are lonely as well,so you'll have to make an effort to meet someone. 

About your cousin, try to figure out why he's suddenly ignoring you. Friends don't just start hating each other for no reason. Maybe there was some sort of misunderstanding? Send him a letter or an email asking him what's going on. 

You should play Nintendo

Your dad put you out, his gf didn't like you, your cousin blocked you, you have few friends.

Man I think something must be wrong with you and you don't realise.
