Badly placed and hard aspects can give health disorder like : lungs, genitale organs, heart, stomach, breathing problems, hormonal abnormalities, accidents related to arms, shoulders or neck, hyper-agitation etc. Relational it can reprezent where you fell lonely and where you wish to have greater understanding and where you would disire to share your emotions. Badly aspected with a sexual planet ( Venus, Mars, Pluto and even Uranus ) can give lots of tensions, obsesions, frustations, agressive tendincies, the worst it can give it's homosexual tendincies or straight.
The lesson of Sappho is to give without askin in return, generousity, understanding, searching wisdom and discipline, perseverance and not to fear to be lonely or restricted.
