Today my feelings got hurt

So this is my first post to this subreddit. I have been lurking here for a while since I am trying to lose weight. I have to say that the progress stories and pictures are really keeping my motivation up and I think it would be much harder without it.

Some Infos about me: 25 year old male 6'1, started with my diet mid january 2013 and lost about 30lbs so far from 399lbs to 369lbs. All I do is calorie counting. I limit myself to about 1500-1800 calolries per day and I try to cut out carbs. I will start working out on a daily basis next week.

Today I was out with friends trying to have a good time and one of them started to talk to me about some video of an overweight dude that flips a table at a magic tournament and everyone joined in saying "that guy totally looked like you" they were all laughing and I tried to laugh but It kinda hurt me since it made me think all they see when they look at me is a fat nerd... They did this before but back then I didn't really care and wasn't even trying to lose weight. Now that I made some progress the first thing they mention about me after not seeing me for weeks is this stuff.

None of my friends know that I am on a diet I don't know how they would react if the knew but as far as I know them there won't be much support anyways.

TL;DR: lost 30lbs, was going out with friends, jokes about me being fat going off -> feelings hurt
