Hi Kate and very warm welcome to our community
My heart goes out to you. Things are so difficult aren't they. Having someone yell and be aggressive is just awful. Dealing with cyclothmania is very difficult and the people who are in their lives also find it difficult. It is not easy living with the highs and lows that come with the condition. Especially those around us, people like yourself.
It is completely understandable how exhausted you are feeling. Saying you are 'too sensitive' is 'too harsh'. Who do you have you can turn to when things get tough? For example, close family member or trusted friend? I'm really pleased you've found your way here. Our community is very supportive and caring.
You sound like you need some TLC yourself. Having CPTSD is not an easy thing to live with and I can see how you would be consistently triggered. So I'd like to focus on how you can make things better for yourself. Are you seeing anyone, e.g. doctor or health professional for your C-PTSD? It does help to have someone who is experienced with childhood trauma.
Relationships are important and to stay with someone. There needs to be a mutual understanding about what's in a relationship. For me, its things such as love, kindness, friendship, caring and support are so important in a long term relationship. What do you think?
Turning off, for me, has always been a mechanism for self survival and it's probably okay to do this. Though, maybe think about whether this is what you want in a relationship.
Maybe he needs to do something about where he is at the moment with his Cyclothymia. Is there anyone who can talk with him about getting further assistance?
You're not alone Kate. Keep reaching out if and when you want to. Though there is no pressure for you to do so.
