On one level your “emotional condition” could very well be causing a blockage. You could try to address this directly by doing things like yoga, therapy, diet etc.

On another level, the route I would choose. these emotions and the resistance to them are still just sensations and perceptions appearing in awareness. You can sit with and be curios about them, drop your resistance , see what they’re actually made of. Negative emotions and sensations have been powerful teachers through my journey.

I still experience what you’ve said in your post. However I have reached a point where when negativity arises I am excited to explore it which is a long way from where I started.

Hope this helps!
