If you think that getting a gf is to solve your problem of
loneliness, you are absolutely wrong!
You should work on yourself first and there's a lot of work to be
done there!
Working on yourself means building up yourself in as many areas as
you can so that yoy prepare yourself to step into the real world
......
essential things you should focus on is performing well in your
studies,training yourself up physically, participating in various
activities and widening your social circle. Have you done well
enough for all these categories?
You mentioned that you are quiet. There's nothing wrong with that
but you could train yourself to be more expressive if you desire by
joining social clubs & ccas.....
What I have stated sounds like the nag of parents, doesn't it? But
of you take a step back and ponder, it makes a hell of a lotta
sense!
