I have a question..

I was diagnosed with anxiety and depression in 2015. This year in January I was diagnosed with ADHD and my med has tremendously helped with my anxiety. I’m amazing honestly.

Well, last month I was officially diagnosed with BPD. So I was wondering, is it really depression I have or is it emotional lows I have from BPD? 

I always thought of myself to be a high functioning depressed person as I never found myself bound in bed, could still shower and do chores, etc. I just had lows where I felt… depressed. 

Thoughts?
