I was in awe last night and I still am that you guys love me that much to do all of that for me...I never would be where I am today without you two...you guys saved me and taught me to be the person I am today. Dad...I love you!!! Thank you for always being there to support and love me as well and always put a smile on my face no matter what :). I'm so grateful for the bond we now share. Alenah the song you put together with Shanelle and recorded for me was one of the most special gifts I've ever received. I'm still tearing up thinking about it. Thank you for that and for your beautiful, special performance. Also a big thank you so much to Geraldine for putting it all together and to @contemporarycatering @robpauerful for the most amazing food! A special thank you as well to Sharon who is probably the biggest reason I was able to get through high school and accepted into college...you pushed me to always do my best and encouraged me...not to mention you were always there for my 1am freak outs about late projects :) Anddddd thank you SO MUCH to all of my amazing family members and friends that flew in to celebrate with us- you guys are the absolute best.
