Lately I've been on a rollercoaster ride. One day I am depressed, feeling sorry for myself, crying, then the very next day I kid you not, I have been in a great mood, bounced back, hopeful and at the gym. Then the next day back in depression. What gives? The only difference in meds I had was addition of gabapentin. I've had similar episodes like this but not as rapid and as lasting as it is now. I've been on this rollercoaster for about two weeks. I'm calling my pdoc tomorrow to try to get me in earlier. I posted in the childhood emotional neglect forum and someone mentioned I sound like I have borderline. Does borderline happen as frequent? Thought answers much appreciated.
