Kiya-
I know that when I graduated from undergrad they told us about a sense of ending and how even though we were ending (and a lot of people had jobs lined up-though not me, but that is another story) and it was a happy time and we were being acknowledged a lot and excited about the changes, we also might feel depressed, and stressed out about the changes. And that was totally normal. We were making major changes. I can see the same thing happening at the end of any degree. Everything that feels familiar and routine is leaving. When I quit work because I was going back to school, all I could think about for a while was where I would have been and what I would have been doing whenever I looked at the clock. Graduating is a major deal.

CONGRATULATIONS!!!!!
