Thank you all so much, you are all so lovely. I am very tired so don't have time to go through and say thank you individually but really thank you (is that enough thank yous?!).
I do agree about colleague being on the spectrum, a few of us thought this before this incident as well due to a few things he does. It doesn't make it feel less upsetting though even though I know he probably didn't really mean it to be hurtful, he also wouldn't have realised that my friend would have shown me his response.
I am not going to let it hinder me in anyway and I won't stop going to badminton (I was there first) cause I really enjoy it 
In general I am not bothered about people not noticing I've lost weight, means they don't notice gains either, I wanted to shout "But I'm trying to lose weight can't you see!!!". Anyway, if I was someone else talking to me I'd tell me that my reaction/responses to colleagues (nice ones and not-so nice one) is more to do with how I feel about myself than what they actually think or do. I tell myself I don't care what people think but obviously I do or I wouldn't have been upset.
Thank you again for being here and listening, I am shit at talking about feelings etc and its much easier for me to write it down and not have to speak to someone.
Moving on....I've had a great day today, I drove up to Aberdeen (165 miles) to visit my friend from Denmark that I met in New Zealand who is here for a week staying with her Danish friend who lives in Aberdeen
did you get that?!
I've just arrived back home after visiting a castle and going for a walk and lunch, it only took me 3 hours and 6 minutes to drive back which I think was pretty good.
Shattered now so off to bed, night night. Love you all
