i feel so sad :(((

It happens to people. We have emotions so from time to time, we can feel sadness or loneliness. But please do not wallow in sadness...Consider it like a bird that flies over your head. You cannot prevent it from going there but you can prevent it from putting a nest there. What I am trying to say is that after recognizing the feeling of sadness, do something to cheer you up...Go out with some friends...Cheer up! Rejoice and be glad..Life is beautiful..

Do get sad. Better to wait for the one instead of getting tied up in a mess with several guys over the years.

I don't know why you would be sad either. But about not having a boyfriend is not such a big deal. You are strong and you can stand on your own. Whatever happens happens for the good. We may not know why but the ultimate objective of this whole thing called like is to make ourselves a good person. So, you do not need a boyfriend to make yourself a good person. Maybe you will have one, but not having is not a big issue.
