Has this person experienced trauma? I ask because these are play by play issues I struggle with when my PTSD is triggered and im trying to process.
If not: it may be a good time to evaluate medications. You build a tolerance after so long and they feel ineffective. This person may be struggling to filter these emotions.
How kind of you to reach out, what a nice support system!
Also Aspys qualify under autism and I know there are a lot of organizations that offer free group and processing training in low key relaxed outdoor settings this person may benefit from if they were open to it and 9 times out of 10 they are.
