17 days - I need help/advice

When I woke up today I felt something different. I didn't feel like I was myself.
I've been going easy mode since I have a girlfriend, and I haven't had sex for a week since she's away for holiday.

Is this normal? I feel so strange when I talk to people. I feel really wierd and I don't like it :/
Is this something that will pass away?
The first week of nofap was awesome and my confidence was high, but now it's all gone.

It also feels that my mind is trying to trick me into PMO just one time even that I know it's a trap.
I'm still going strong, but I need to know. Will this strange feeling of insecurity go away?
