This is normal. But you do need to return. The reasoning behind your not wanting to return are many, imo. You have done well in taking a true vacation... a vacation from the stress of your disorder too. But now you need to return to your daily life, and that needs psychological attention too.

Since you now have a "norm" to shoot for, you can better gauge how fast or slow you need to go in therapy. If you begin to become ill again, then you are going too fast (covering too much material to work on.)

Good wishes!
