300+ days PMO Free - Strong anxiety coming late in recovery

Hey guys!
I have been in recovery for a long time and are currently doing quite well. I have made it for 300+ days, and mostly I have felt good, HAPPY, inspired and strong in life during this process. A lot of good things have happened. I got a job after graduation, I ran my first marathon, I have got a girlfriend that I love. Stuff that never would have happened during my addiction.

But... For the last month or so I have had mental struggles. Strong anxiety. Fear. Worrying. I have been seeing a psychologist, reached out to friends, family, therapists. Tomorrow I have a doctors appointment. It feels like I’m doing it all. And I have searched within me for answers, turned everything I can think about upside down to find What’s bothering me.

This could be a depression or something else - i Don’t know. But maybe it could be common when longer in recovery? That thought struck me now... so I would like to ask for advice from other fellow people in recovery, who are approaching or have approached a year or so in recovery. Can you relate to this? How did you handle it? Feel Free to share.
