I have been diagnosed with BPD. Recently, I’m starting to think that I might also have bipolar disorder because of my sleeping habits &amp; periods of “highs” &amp; “lows” that last longer than just an hour or so. Last night (well this morning) I only slept for 2 hours. Today I have been fully functional without feeling the need to sleep. And right now I kind of feel like I’m at a “high” point. Although, I’m not sure if this is just what being happy is supposed to feel like. I also have major depressive disorder and have been diagnosed with PTSD in the past. Any input or would be greatly appreciated.
