Not worth hiding and there is nothing to hide from. You have as much right as any other person to be who you are. You are not odd, strange, you are not a person to be insulted, ignored or embarrassed. You are a perfectly normal young woman with a few physical defects.
Been ages since I was in California, there are BTW lots of girls (and boys) from Cali on Susan's so you can get to know new friends. Are you a beach babe

, we have great beaches in SA but the local surf isn't that good, OK but not great.
In fact I spent most of the afternoon at the beach side shops at Glenelg (you can google it and see where I live if you wish) it was a nice day, a bit humid but people were all in a happy mood. Well I was anyway
