What in this chart makes the person prone to fits of anxiety and depression?

what i seem to notice, is that the people with contradicting sun and moon signs often causes it . if you don't have enough time to think deeply within herself. I have 2 taurus friends, one with a cancer moon (depresserd, seeks too much security) and one with a gemini moon (happy go lucky, sweet girl) Cancer sun/Leo moons are usually very self controlled on the outside but seek too much on the inisde. I suggest the owner of the chart think a little bit and settle their downfalls.
