If the psychologist is suggesting an assessment, go for it. They have knowledge and experience with neurodivergent people and their vibe sense may have picked up that you meet some criteria. Also it’s not either/or, people can have both autism and adhd. Throw in some trauma, depression, difficult family situation etc and it’s not gonna be easy. You are doing so well trying to get to know yourself as look after yourself. It’s not always a smooth road. But it will be worth it.
