It feels kinda awkward being with your sister who now is becoming a true stranger. A bit of a reality check for me. It is what I wanted in replace of a toxic relationship
This sounds sane and brave to me, Seasons.
I think you'll be just fine at the shower if you say to yourself, There is enough love. In this universe, we are all surrounded by it, no matter how awkward and small we feel. There is enough love to go around.
If you just walk around in that state of mind, feeling it, you'll be able to love yourself and be in her presence with no harm to your sense of self.
In a way I think you are a better sister and daughter because you are behaving truthfully.
