Your Venus squarring the Moon has a very strong aspect, because these two are also in reception.
The house of friends is full with plenty hopes (Jupiter, ruler of your 2nd, the house of hope, Saturn, ruler of your 3rd and 4th = brothers and family, and this Saturn between Moon -significator of family, too- and Jupiter), so, what could that mean?
You say that you are sad. Your Mercury in exaltation rules your 8th. Are you thinking mostly on death? Did you have some loss in your family (brothers or uncles or so ) ?
Your Venus rules your 12th, therefore I think that Tim is right, too. Something is strange in your feelings and your joy, because it isn't open, if you can understand.
If you lost a friend and you experience an affective broke - there are reasons enough to be sad, yes.
Actually the Sun conjuncts your ASC, that will you give a clearer insight to your essential being, like to become more conscious, and that makes always suffering. But suffering is not only a bad thing, as you know it yourself (Mars in the 12, you understand
), and therefore look at the good perspective of this situation - there is surely one!
The best you can obtain, is to do not fall into too much illusions - look at your Neptune in the 2nd, the house of hopes -, therefore your Sun, actually, helps you a lot.
Cheers
