I actually convinced my partner of 5 years of communism. Yes it did become my personality and yes I could not shut up about it but thats part of what they love about me
Voting is not political activism. Its actually the least important form of political participation. Yet, America still can't get 40% of its populace to engage with even that. Try forming a union, creating propaganda, hosting educational seminars on politics and political history, or feeding and housing those who can't afford to do so themselves (Through a group/org not as an individual obviously). These things are political activism. We complain a lot on the internet because it is very frsutrating to live in a world where the vast majority of people think the most important thing they can do is vote for one loser who hates you or the other loser who doesn't give a shit about you.
Not everyone has an "inner voice". Having one isn't anything particularly notable either. Humans seem to conceptualize there thoughts in a variety of ways and none of them signify your intelligence imo. For me though it is a very literal inner voice. I conceptualize my thoughts using internal words or pictures. I will even speak to myself directly through a sort of dialogue. I think it comes from reading a rediculous amount of books as a kid.
Something that helps me when I am overwhelmed with emotion is to isolate myself, write my feelings down, and then come to my partner and discuss them when I am feelings are more stable. I just write small notes so I can remember but explain them more fully verbally. When it comes to intimate touch my partner will make sure I am comfortable enough to engage or just let me make the first move.
I honestly recommend reading about autism and how autistic people think so that when she tries to explain things they are easier for you to understand. I wish I had resources to recommend on the spot but I can't remembee them by heart
Edit: speaking very directly is also fantastic. Tell her exactly and directly what you are feeling and what is making you feel that way. It is as simple as "I am feeling ________ because of ______ and that is making act like _______"
90 daily is the average Texas summer. I cannot wait to permanently get the fuck out of there
