I don't think life is for me, I'm not being suicidal or anything but I feel like I'm behind in life and I don't know what I truly need to want.
You feel like you are behind because you are comparing yourself to other people.
But you know what, you are ahead of so many people and are even fortunate enough to have a computer and are fortunate to be alive. There are people in 3rd world countries and in war zones who cannot even think “I don’t think life is for me” because they are trying to survive. There are people who are sick and have misfortunes beyond their control and they still fight for life.
And you are telling me “I don’t think life is for me”? You are more fortunate than most, so stop comparing yourself to who you should be and start fighting for who you want to be.
[Also if you believe you are depressed or anything of that nature please consult a professional.]
