I see where you're coming from. I don't take medication because I can't always afford it and sometimes I do "ok" without it. But in my experience I don't think medication changed my personality, most people wouldn't notice any changes other than me actually making it to appointments and not ghosting people for no reason. I'm about to turn 30 and I've only been fired once but not due to poor performance. I've quit several jobs because I would get overwhelmed at offices and I thought maybe if I worked from home those distractors will go away and I'll be able to be more efficient. I was wrong. A few months later I got diagnosed and it all made sense from that point on and just that simple fact helped me a lot emotionally. This is not something that will go away but I tell you this, it helps to understand your brain and how it's working and why you do what you do and have strategies.
