Moodyness is one of sc moon charasteristics. And cancer is a moody sign too. I think moon aspects can play a role here . Do you maybe have moon uranus conjunction?

From one Cancer to another Cancerian....

Well I have Cancer Sun, Scorpio Moon, Sag Rising and I used get this way. As a Cancer, being the most complex sign in the zodiac, I understand what you are talking about. I used to get that way a lot when I was younger. I have noticed that Cancers as they get older have to go through an "inner" quest. We are very in tune with our surroundings, sometimes too much like a sponge and soak energies around us good or bad and that then affects our own energy. (you are probably grinning cuz you know exactly what I am talking about lol.) As I have gotten older and more and more stronger and secure with myself (I was insecure about my feelings and certain things when I was younger, preteens age.) As I went through things, made mistakes, observed and felt things in the under currents (becoming more in tune and trusting myself) I became confident, secure and stronger. I am not questioning your security at all by the way but explaining why and how I overcame the tribulations. As a Cancerian brother, I understand how it feels that no one "gets you" and that is because when we vent out, many times we do not get the same in return when other people confide in us, as we throw our whole being into those we find very close in our "inner circle". Sometimes people come off as cold, brash or unsympathetic to our feelings because our feelings run VERY deep. (especially being double water sign.) But have no fear and as far as contradiction...Cancers are very contradicting, because it is all about that very moment and fuck whoever do not like it LOL, besides, It can be fun because just when someone thinks they know you, you throw them for a loop. I go by this saying..."Either love me or leave me alone." If you have anymore questions or feel you need to ask me something in private, by all means, if I can help...I will.

Hope I was of some help sweety...
