I'm not being too specific here but will try to provide enough info for people to offer sensible advice!
I have just started a new training scheme and there is a man on the same one who I have developed a bit of a "thing" for. He is probably about my age, but is very tall, good-looking, well-muscled (he obviously works out) and seems to be a funny, easy-going type (although I don't know him at all - this is just based on superficial first impressions). I'm not really used to being around such exemplary specimens of manhood (!) and tbh I'm finding myself getting a bit distracted by him...
I am fat, unattractive, and very obviously do not work out. He is not going to be interested in me. I am most certainly not going to make my feelings clear or try to flirt with him, so I'm not looking for advice on how to do that. What I would appreciate is ideas for how I can not be distracted by him when I'm supposed to be learning, and stop the intrusive thoughts that keep creeping in. I am quite embarrassed that I'm getting all flustered over a bloke at my age!
