I have to say, I face a rather similar situation, although part of my reluctance for asking for help comes from my own views on ADHD(That it's over-diagnosed), and mental health(God help me I don't want to be crazy).
I'll be 23 next month, am a staff-RN in a Rehab hospital, where we usually have between an 8:1 and a 11:1 patient nurse ratio. I've worked there for almost two years, and am fairly successful in getting everything done and patient care. Unfortunately, I still get that disorganized panicked, "OMG, I'M RUNNING LATE, I'M NEVER GOING TO LEAVE THIS PLACE" feeling a lot. My co-workers are always like "Breathe, Amanda." At times I can hyperfocus at work, but I usually end up frazzled at some point. And I've had a few issues with discipline(Mainly because of foot-in-mouth syndrome)
At home, however, my disorganization is even worse. That's where I actually see the biggest problem. I can't sit down and watch an entire movie straight. It sometimes takes me days to watch an entire movie, because I'll pause it, do something else, get distracted, watch it for another few minutes, get distracted again, go off and do something else...
So, I was looking into ADHD for something completely different, and every time I read the symptoms, I was like "THAT IS ME!" Now I'm faced with the idea of getting diagnosed, because I do want to be better, but I don't want drugs, because I dislike drugs, and I can never remember to take drugs anyway. And I don't want to be diagnosed as mentally ill, because, well, that's just my own stigma, and if it's not official, it doesn't count right?(Right).
Nevertheless, I am going to call a mental health provider and get it looked into.
