Hi, I can relate. I am biracial (before that was as common as it is now) and got called horrid racist names my whole childhood. To make matters worse my parents somehow found a way to drag me all over the world during my early teens to be called every racist name there is in the world. On the lighter side I never got a called a 'whitey' until after my 40th birthday - the only name I had never yet been called - and it took Australian Aboriginal racism to do that!!!! It definitely effected my sense of self and worth and where I belong.
I am sorry that you have experienced this type of bullying as how we look (in so many different ways) is so far beyond our control and frankly looking back, I am glad that I was so unique that it clearly threatened people but that's just part of my warped sense of humour.
The best advice I can give you is that there are better people around - not many - but they are there and the truth is that you will only truly have a very few real friends throughout the course of your life. That's not to say that you can't socialise and have fun but when it comes to true friends they are few and far between and the trick is to identify when you've actually found one and nurture and hold that friendship dear. I myself have only really had 2 real friends and I did not meet either of them until 40 years of age once I had well and truly accepted my state of depression.
You can still live and go on each day and there are still social times and enjoyment even after a diagnosis of depression.
I wish you all the best.
