Hi,
I wasn't quite sure where to post this... I have Schizoid Personality Disorder (self-diagnosed, as most of the cases). While I have always been a rather laid-back, introverted person for most of my life, something started changing since about a year ago.
It started back around March-April 2015 when I had this "phase" (don't want to call it "episode") when I was very irritated and angry at everything. I just felt very moody, including moments when I felt full of rage and I just wanted to be left alone. Then a couple months later something changed. I started working out, eating healthy, going out with friends... I assumed I had just overcome a rough patch and that the summer had boosted my mood. Then everything changed again in a few weeks and I have been having these constant mood swings ever since. They alternate between "feeling empty/dead inside, locking myself in the house for weeks, not wanting to talk to anyone, lack of energy, feeling desensitized, angry...." to "feeling happy, full of energy, being confident, wanting to socialize, seeking new opportunities...". It's become quite bothersome because at first I thought it was just phases, but it's come to the point that I feel like I'm two different people and they're just taking turns every few weeks.
I knew of bipolar disorder, but there's no way I fit that description. I haven't been manic to the point of harming anyone or losing control and I also haven't felt totally depressed (but then again, I can't really feel sadness due to my SZPD). I know I have to wait for at least 2 years, but I was wondering if anyone else here is also schizoid or if you've read about these disorders being comorbid.
