Oxymoronic and Confused :/

This blog post has been a long time in coming. It's something I really need feedback and help with but...it's hard to put into words so just hang in there...

Basically like (most) everyone else, I have different aspects to my personality. I have my serious side, my sentimental side, my nerdy side (takes up a lot of room), my kind and generous side, my humorous side and my sarcastic side; yep I have lots of sides. My problem is...what side should be dominant? I feel like at times, one aspect of who I am can steal the limelight and be at odds with another aspect of my personality...a while ago my (now ex) roommate told me that I was too sarcastic to be nice; let me tell you that comment hurt! I've always considered myself to be kind and caring; when I was younger I wanted to be Mother Teresa :-) I love making people's day and making them smile. But is my sarcasm overshadowing that?

Take this blog for instance, I want to be able to express my lighter, random side, but at the same time, I want to talk about controversial issues and things that are near and dear to my heart...like ALS and losing my best friend...

So what do you think? Is it possible to be nice and sarcastic at the same time? Also, at what point do you stop being nice? I mean, where do you draw the line and put yourself first and others second?
Your thoughts? I could really use some advice :-/ If you don't feel like posting a comment (even though you should =) you can email me at RantsRavesRandomocity@gmail.com)

That's all for now folks
