Changing your given name

I've been thinking about doing this since I was small.  I absolutely hate my given name - it's long, too many syllables and I've always struggled to pronounce or even hear my own name.  I shortened it to something more easy to say aloud, but still I cringe.  My name also was said alot in vain growing up as I was misunderstood and wasn't diagnosed until very late in life -  so it's traumatic to hear it and I always feel like I'm in trouble when the full version is spoken.

I thought up a better name but am having cold feet due to thinking I'm just being silly.  I feel like I don't know what my identity is and my name is just associated with negativity I think.  Users here may have spotted that I change my profile username alot because I just can't settle on 'me' either anonymously or IRL.

I'm really interested to hear others' views on their own names, do you like your given name?  And do you struggle with what your name means to you? ie. your identity.  Hope I'm making sense!
