Definitely sounds like you're tolerating a lot at the moment
- The IUD causing you pain
- An inability to freely experience the natural joy and excitement that can come with sex
- Perhaps people around you not listening to your needs (including work colleagues)
- Mental health challenges
- Not knowing why you're triggered to anger so easily
and the list goes on. That's a heck of a lot to be tolerating in life.
For myself, I can remember having some major revelation not too long ago. It was quite a wake up call. There were a number of things and people in my life I was 'tolerating'. When I realised that most of the aspects I was tolerating would, for some people be intolerable, I thought 'No wonder I'm getting so angry, so often. Life is not meant to be this difficult. Life is not meant to be tolerated'.
Regarding the IUD, is it possible to have it swapped for a Mirena (non copper IUD)? Personally, the Mirena has never caused me any issues. Basically, if our body can't or won't tolerate something, it'll definitely let us know (like in your case). We should definitely not be left to experience such dis-ease on a daily basis. Any doctor who fobs this off as 'normal' should be seriously questioned.
From my experience, if you're a sensitive person...you'll feel life. So, if you feel a connection to life through the excitement of sex, the excitement that comes through a certain well being routine, the excitement of new adventures (adding new ventures to life), the excitement of interacting socially with people and so on, you can also feel the impact of a lack of excitement, a disconnection. Kind of like a numb feeling or a nothingness at times. Living in Melbourne, I can relate to how potentially depressing a lack of excitement can be. How does it feel to not go to the places or follow the routines that excite us? How does it feel to not interact with the people who typically vibe us up? In general, how does it feel to not be heard when we're so desperate to be heard? Make you want to scream? How does it feel to be tolerating what is actually intolerable (but we remain the easily triggered champion who 'toughs it out')? Our 'feelings' or physical emotions are highly significant when it comes to how we're feeling life. Wondering if you're feeling like a human pressure cooker at the moment, occasionally blowing off steam.
Sounds like the IUD could be the #1 issue to address. If all we're feeling is pain, it can be almost impossible to feel anything else.
