It could be a shock at first, since Neptune is leaving 12th house home and coming to its Piscean home. Change of speed. More softness. New naturalness. Whatever you were inspired artistically with Neptune in 12th should materialize, along with a disproportion of how you see yourself vs. how others see you.
I think your separation from your pet turtle symbolizes this transition, since with Neptune on the ascendant and opposing Desc. it may make sense that the significant relationships which rounded up your identity may be dissolving now. Happy drift!
This is a time when your way of interacting with others will change. You’ll find it challenging to develop any sense of self-knowledge but you’ll need to do just that as you discover new facets to yourself through others' eyes. This process will give you the opportunity to attempt to see yourself as others do, but it’s not likely to be as successful as you’d like since you’re still changing according to every person and situation you encounter. Mind you, others won’t be inclined to know you well either at this time, but the process of learning will be based on your knowing who you are, and how you project yourself to others. Be aware that you’re not necessarily going to show the real you. It’s only who you are at this time.
It’s a confusing period. Your interactions with others are likely to become a challenge in their own right because they’re not really seeing you clearly either. Another issue is the likelihood that you’re not going to be getting clear answers yourself since it’s a very confusing time period. Despite your wishes otherwise, you really need to be focused on being as real as possible.
Look as well for relationships in which you can offer compassion, to help others, or to expect others to help you, but you’ll need to be alert and avoid any possibility that the needs you’re expressing right now aren’t necessarily who you really are. Avoid, as a result, any tendency toward co-dependent relationships. That alone will be a challenge because you’ll almost wonder why they’re seeming to come out of the woodwork!
Hope it helps.
