You can try to keep masturbating. No one can tell you, what will work 100% in your case, because every man is different and all reboots are different as well.
The important thing is, wether you get progress or not. So you can try and just quit porn, but keep masturbating and having sex (I assume you have sex, since you said you have performance anxiety). If after a few months things haven't improved, you can still quit masturbation for a few months at that time, when you need to adjust your reboot to find out what works for you.
There would also be many good reasons, why you could just stop right now though. Lots of guys did not feel, that masturbation helped with the reboot and you will find many accounts saying, they think masturbation held them back. In the first six months, I also made a point to really reduce MO and sometimes was able to stop for several months.
