This is really interesting to read, as I am like this. I absolutely hate it about myself. I don't act on it - I am a kind and supportive person but not intrusive or gossipy. I do go out of my way to help people and used to be a terrible people pleaser but I am more aware of it now and make sure it's wanted, and I have my own boundaries.
It's awful. If I hear a friend is having a breakup for example my gut reaction is excitement and almost relief. My friend is pregnant and she was going for a scan, and my first intrusive thought was the drama if she lost the baby.
To be very clear, these thoughts are intrusive, not wanted, and distressing to me. It's subconscious, they pop in there without my permission if that makes sense and they're not well formed or deliberate if that makes sense. Having thoughts like this around your friends is really shocking and feels like I have an evil alien in my head. I was incorrectly diagnosed with OCD when I was younger but now know it's ADHD which I was then diagnosed with 15 years ago. I also really struggle with ear worms and thoughts of self harm. If I'm cooking for example I will get flashes of thoughts around sticking the knife in my eye or putting my hand in the blender. It's really horrible.
For me I also think it stems from having an identical twin and competing for my parent's attention, and also being badly bullied. I have very poor self esteem as a result and life feels like a big struggle. My life hasn't returned out how I wanted and I think it's a bit of relief that I'm not the only one who struggles. I want things to go wrong for my sister, and she is the same for me. We never let on about this but I think we both subconsciously are aware of it. There is a huge amount of jealousy and envy on both sides. With my sister it's harder to control.
Again, this is subconscious and my brain's knee jerk reaction. I don't sit there lavishing in these thoughts or entertain them. I recognise them, challenge them and form my 'true' thoughts. It's hard to explain, but these negative thoughts then change if I engage with them and think about how I actually feel.
I remember watching a comedy programme a while ago about a woman who had intrusive thoughts around sex, and it feels a bit like that.
Just like many people I have personality flaws mostly from my childhood. That's not my fault and doesn't make me a bad person, but it's my responsibility to work on it to make sure it doesn't affect other people or myself any further.
I would highly recommend therapy and ongoing self help, it's something you can work on and for me it has been a relief to discover it's not my true self. I used to think I was a really awful person.
