Mood swings and ocd

I’m constantly finding myself getting irritated easily and sometimes it even confuses me because I was happy and fine two seconds ago. Like I feel emotionally unstable. I also randomly will get sentimental or sad and I just start crying. Is this just me??

Recently I’ve been getting these very intense episodes of feeling extremely annoyed, irritable and touchy. I start to think narcissistic thoughts like feeling extremely entitled, envious of others and just overall snotty and rude but also horrible about myself. I take everything personal in these moments even though I know it’s stupid to do so. with harm ocd it also makes it 10x worse because they urges are worsened by the anger and intense emotions and sometimes I feel like just crying or this deep pit in my stomach of fear and dispare about the future like where am I heading and who am I becoming? I’ve excessively been on Gemini asking about covert narcissism, because my family disagrees with the idea of me being a narcissist along with my therapist but I just can’t let it go because I actually genuinely believe it. When I want to make things right it feels so self centered and I don’t know the right way to genuinely care about others. Maybe I already do?? I can’t tell if this is all just anger, intense fear and overwhelm, from med changes (went from lexapro to buspar) or processing grief (grandpa died in February) but sometimes I feel even worse because in my head I believe the grief only effects me and I need total attention and care 24/7. and start wondering if this is a subconscious way of thinking for me that I just assume is ocd and anxiety. I feel so tense and when I get in these moments I feel like I’m about to combust, I dissociate, feel like sobbing, isolating, or yelling but can’t tell if it’s all caused from an “ego blow” or something that someone did that made me feel bad about myself and that’s why I feel such high self pity. idk anymore but this feeling is terrifying especially the more I believe I’m a narcissist everything is evidence. I even start wondering what if this is rage, or hatred or resentment? like deep down dark feelings?

My current obsession is around mental health, specifically that I have undiagnosed Bipolar 2. Any changes in my mood are triggering and in my compulsive googling to make myself feel better (never works lol) I discovered that ocd and bipolar are linked in like 10-20% of cases?! So now I feel worse. Anyone else experience mental health fears?
