I have had anxiety for the past year, starting when my best friend moved away around this time in 2021. It got really bad and I got prescribed Mirtazapine, which kinda helped with sleep and the additional depressive symptoms, but I would again and again easily get triggered and get anxious. 
A minor inconvenience would sometimes spiral me into rumination. Also when it suddenly starts I always project it onto my relationship with that great woman I met 6 months ago. Fearing she would leave, betray me or that I am not good enough for her.
When I have phases of no or low anxiety those fears are completely gone. 
I was quite well for the past 5 months, but suddenly a few weeks ago it hit me again, full force. Then after 10 days it went away almost completely, just to come back this evening before my doctors appointment.
But I am wondering, am I anxious enough?
I mean, I am functioning well, going to work, working out going out. But there is always that lingering that suddenly I could get an anxiety attack again. Also I should add, that I never had a panic attack or anything.

What are your takes?
