There is always hope. Pisces Sun people are sensitive, psychic, creative, but like all kinds of people and don't judge them. Having the Moon there means you are emotionally spiritual, romantic, caring and nurturing. You care deeply when you love and are very forgiving. You are changeable too. Venus in Pisces means you are fun socially, a good storyteller, kind to friends. Be careful not to let them take advantage of you. Mercury rules the way you think, so your thoughts are ruled by your emotions. As long as you are aware of that, that's OK. The Mars rules what you like to do physically, so in Sag, it makes you stronger and more outdoorsy. If we had a whole chart, we could see if the Mars squares the Pisces planets tightly, that would cause challenges depending on what houses these planets are in. But there are still five more, and they are in other signs. It's not unusual to have 3 or 4 planets in a zodiac sign, often the Sun sign. It's nothing to worry about. Take care.
