A Waxing Trine between the Scorpio Moon and Cancer Sun (29 deg) helps you integrate depth with empathy and nurturing with courage. You can go deeper but still be safe - empathy is enhanced by an unflinching look at what's in the shadows.
This influence allows the natural expression of profound emotions, with no fear of rejection. At this point, it's not "too heavy" - it's time to go there. Note that this is the final degree of Cancer, and the Sun will enter Leo a few hours later. So this is also a turning point - perhaps a barrier is dissolved and beyond it lies different country (with a reason to celebrate?) Cancer to Leo takes us from introverted and self-protective to extroverted with everything on display. Consider how this transition might be connected to any emotoianl breakthroughs you have today.
