It is important you have someone to come in to care for Reya when you are away.
It will be fine to leave her for a week with friends coming in to feed her, change her water, clean her cage and play with her.
She will be just fine. I have multiple birds and had them cared for by a trusted friend when I was away for about 10 days.
Every one of the birds were just fine. Reya will miss you but she will welcome you back when you return.
