I've NCed because this is personal and I have family on MN!
I'm asking here first because I don't want to go to the doctor and waste their time if it's not needed.
Since I was a child I've had problems with getting overwhelmed if there's too much going on around me. For example I find it very difficult to sit in a room with music playing whilst talking to someone because listening to the music AND concentrating on the talking feels very overwhelming. When I say overwhelming, the best way I can describe it is it feels like there's a swarm of bees buzzing around in my head/body and I start feeling too hot.
This bee feeling happens with other things too. For example if I'm visiting a city and there is a large crowd and there's lots of people around me. This is especially bad if I'm lost and trying to concentrate on finding my way as well as dealing with the crowds/noise. When I feel like this I also get very irritated and snappy at the people I'm with 
I rely heavily on lists and routines and get very anxious/irritable when I can't follow them. When I'm trying to plan out my evening in my head and my partner says 'we'll make dinner and then see what we feel like doing', I find this very stressful because I'd like to know what comes next after dinner. (I promise I don't let this show, we're in a loving relationship and I'm not a complete killjoy).
I suffer from extreme anxiety and I'm on medication for that. My main anxieties are worrying about not setting my alarm so I miss getting up for work (this has never happened but I check my alarm 10+ times during the evening just in case) and I'm a very 'what if' catastrophiser (if that's a word!)
I wouldn't usually run to the doctor but getting overwhelmed by the littlest things is really affecting my daily life. My partner suggested looking into autism - does this sound like it would fit?
Thanks
