I started seeing my pdoc in fall of 2012. Around this time, I went into the hospital for suicidal ideation. Little medication change, things were pretty good until spring of 2014. I relapsed hard, purging, cutting, not going to classes. 
My therapist asked me to start coming in 2x a week, which didn't help and just cost me a ton of money. My pdoc upped me to the maximum dosage of my antidepressant. This really messed me up and I completely broke down and had to go home for the semester.
I returned last fall, feeling much better after seeing a good therapist in my hometown and switching medications. I was doing pretty well. 
But for the past month or so, I've been having symptoms that I've never really had before. I can hardly sleep, I can't focus (it takes me forever to read a news article) and I just feel anxious and overstimulated all the time. 
I saw my pdoc this morning for a regular appointment, but made some of this new stuff clear on my intake sheet. He brushed it all off as stress (I'm working about 25 hours a week this semester.) 
I feel like saying more would be pushy. I just think that after three years, he's not going to be open to looking into yet another diagnosis. It feels so stagnant. Our appointments are 10 minutes, tops.
Maybe it is just stress, but I just don't know how to approach this.
