Don't shy away from your feelings. Being sad is a perfectly fine emotion. You lost something that meant a lot to you, so feelings such as these are inevitable to follow. I am sure you let her go to a good home (they may be able to follow u with pictures/updates) so I am sure she will live a long and healthy loved life.
Just remember that in the future, after this amazing time in your life, that you will be able to have this experience with another reptile if you decide to. Life moves on and time heals all wounds.
Keep venting if need be, we will be here to help you through.
