Most Helpful Girl
There's your problem. You've never asked out a women in your life so how are you supposed to start a love life when you don't put the effort in? With my partner I liked what I saw and I said hi and we got chatting. When someone talks to you it's obvious when they like you or like what they see so in return you might get it back.
You've made yourself feel lost and defeated by doing nothing. Try doing something and you won't feel that way when you succeed. In my opinion being with someone that you love and they love you back does make you happy no matter how angry or upset they make you feel. Love is the greatest thing in life that you can give and receive.
