I Am Going To Miss My Sister

I leave for college in 2 days. My sister and I have been having an affair for over 3 years. I love her so much and I know everything is probably going to end soon once I leave as this obviously can’t really continue. She is about 3 years younger than me but our relationship has always been really strong. I am feeling so many emotions because I don’t want us to end and neither does she. We can’t get enough of each other lately as we know it’ll end soon. The sex has always been phenomenal. I don’t know if I’ll ever find someone I feel so strongly about as I do her. I’ll always love her and I always will look back on things fondly. Sucks because I think we both knew it could never last. Not really looking for advice or anything, just sad and wanted to pour my heart out somewhere.
