Girls are out of my reach
How are they out of your reach and what do you want from them?
I can't get a girl to be attracted to me.
I'm sorry you feel like you can't get any girl, but it's great that you limit yourself reasonably. If they are out of your reach, you can only do things to improve yourself so that they are in your reach.
I can't do that, it's too hard.
I am sure that you can, by starting step by step and improving yourself slowly, and try to then have a more positive outlook in your life so that more people would want to be around you.
