Messa,
I won't repeat to much the excellent advise you have already gotten.
Second hand smoke is never a good thing,
You won't lose your social life, you may be able to change it slightly to suit you a little more,
You will need to come up with new things to do,
Going outside in the warm weather is always a good idea, if your friends want to smoke then this might be better then the smoke box they seem to like so much. Go out with them if you want, but have your straw or bottled water ready.
Keep firm to your quit, do not let anyone tell you differently. You are not the outcast. If anything you will live longer and have to find new friends :)
Your doing fantastic, so stick to it and give yourself the time to breathe and do what is best for your body.
Keep posting we are here to help,
Josie
