am i developing ED because of OCD? help...

Is this a sign that i'm developing and ed? This has happened 3 times in the last month and a half...

After i ate i felt really full and suddenly felt so gulity about eating it all and getting this thoughts in my head that i will become fat because of this. In a way it felt comforting eating all that food because i thought "i will just purge it out later".

Now, i can't stop thinking about this...i'm afraid this will escelate. I also have ocd, for which i am starting therapy this week. Is this something i should mention in therapy?
