Fortunately there are many many people who appreciate other things than merely drinking, random sex, drugs and superficial interaction with others. They are there even if you might not see them right now.
I tend to associate with such like-minded people and these interactions are meaningful to me.

On the larger topic of the meaning of life, I have thought a lot about this and I believe that at the end of the day, the most important thing is that we LIVE our lives and experience them. By that I mean, experiencing happiness, sadness, fear, longing and other emotions as well as thoughts by being in the present moment and alert.
Yes, happiness is one part of it, but only one part. The search for meaning is a part of it, but that can already be found in living life to the full at least to an extent.
Sorry if I'm rambling on... I'm just trying to formulate my own thoughts. I think asking the question about the meaning of life makes you truly human.

I don't feel I can contribute much to the love theme, as I struggle with this myself, but I hope the above has helped to give you a different perspective even if you don't agree.
