--- again with the REALLY long posts ... i've seriously got to conform to like a 300 word maximum. sorry bout that, i get verbose a lot of the time! ---
Buttercup -- I've thought about your thread here since you posted it, and have been trying to think up what I want to say. Basically, to sum it up ...
You remind me sooo much of my younger sister when she was your age! (well, except for the horse parts) :) I'm going to explain her to you a little, and see if this helps...
When she was younger, she would fight with her friends -constantly- and she was unhappy a lot of the time. She missed a lot of school, fought with our parents all the time, and fought with me as well. My sister is a passionate and vocal person, and often people just don't get her. She isn't the most tactful either, and has often rubbed people the wrong way. She has covered herself in tattoos, piercings, and dresses in black, so getting a conventional 9-5-work-in-the-office-cubicle-world will likely never be for her.
But ... she graduated from college, and now works as an Adult Day Program Coordinator for Social Services, and the old folks --- THEY LOVE HER! Shes passionate about what she does, and is a very vocal animal rights activist.
So, I guess what i'm getting at is that there is a place for you in life, no matter what. How you deal with the people around you will dictate in a lot of ways how they deal with you as well. My sister has lost -many- friends over the years, and has gone though many many hard times. If you are rude, and hard to be around, then you will have to be prepared for people to be rude and abrasive back - it is human nature. My sister has gone through the same things, and it is her choice to act the way she does, and has accepted the fact that not everyone will like her because of it.
Because of how she dresses and is pierced and tattoo'd, she HAS limited her work types - she will never work in an office like I do, but she has found something she loves to do. She was lucky, in that where she works and the people she works with accepts her for who she is -- not everywhere or everyone would be willing to give you the same acceptance (judging by some of the responses to your tattooing here). That is also human nature.
Even with tattoos, theres a lot of places that it doesn't matter as much - IT departments, a lot of social work places, Art and Graphic Design, Marketing, and more progressive companies to name a few. Dealing one-on-one with customers directly will likely -not- happen with heavy tattooing though, so you're limiting a lot of the kinds of jobs you might be able to get dealing with the public. Also, getting a job with tattoos is more likely in a large city where people are more used to that (like Toronto), than smaller towns might be.
I'm not going to preach on the school thing - that seems to have been covered already by other posters - the only thing I would recommend is to learn how to learn - school is good for that. It will help you once you are in the work-a-day-world, since every day you will likely have to learn new things and apply them to your job.
My sister and I are almost completely opposite, and we've had a lot of differences over the years, but we love each other, and I've accepted who she she is both physically and emotionally. I hope that the people in your life (family, friends, etc.) accept you for you as well.
Now, I'm not saying that certain behaviours, or being rude, is by any means ever a cool thing to do. All I'm getting at is that you will need to be prepared to deal with the people around you reacting the same way back if you
-choose- to continue with the actions and behaviours. No one else can be responsible for you but YOU.
... and since the Tattooing thing has come up quite often in replies, heres a story about my sister and tattooing, and people being judging of her and it. I worked in a Toy Store in a large mall near Toronto for about 5 years. I am clean cut, dressed conservatively, and was working cash. My sister and 2 of her male friends came into the store - spikes, dreadlocks, black and purple hair, piercings, tattoos, you name it. There were 2 women at my cash - about 40-50 - they look at my sister, and then one says to the other "Oh, look at that girl - she must have a lot of problems to look that way. I bet her mother has issues, and probabally never spent time with her". I turned to the woman and said "Actually, OUR mother was home with us until we were 10 years old. Thats MY sister that you're talking about, and shes perfectly fine thank you. Heres' your change, have a nice day". They turned red and left the store.
The moral? People will judge you behind your back based on how you look and act. They may also judge your family and the people you hang around with based on your outside appearance. But for the people doing the judging well --- you never know the whole story, so maybe think about it before saying something rude.
