Why does your sister sound so much like somebody I know from High School three years ago? Well, in any case, I don't know what to say. My dad doesn't really look at art as a money-making potential kind of job so he advises me to stay away from any artistic jobs just because they don't provide a good pay, and that it'll make having a living a bad time, although he would still be supporting...but nonetheless, I can imagine, so I chose to be a nurse.
And hey don't be afraid, I had to get some things off my chest here in the thread as well. I confess that edited my posts out for the sake of my own privacy; I don't want the internet to get in the way of personal issues to be honest. Does your dad want you and your sister to have a certain job or something? My dad pressured me to be a nurse, but I can't say he succeeded. For him, it's all about money, that's not the reason why I wanted to be a nurse. I just want a good living, and the job satisfies the goal.
But I admit...I know exactly who I am, but no matter how hard I try, I am not everything I want to be, for I have no desire. I don't want to be a nurse, but neither do I want to be a Game Developer or an Artist. I used to have a desire for those careers. It's not the same anymore.
Everytime I fail or do something wrong, I am met with a wall of insults. Sometimes I just can't take it. Other times I can just suck it up. The worst insult my dad could say to me, and he already has, is that he is disappointed in me or that he has lost all expectations in me.
Same here. Sometimes when I see my dad treat my little brother like shit I just want to stand up for him because he's not that much of an idiot. Hell, he's got better grades than I do, and yet I'm the smart one? He's a smarter gamer compared to me, and he's even an artistic person. I wanted to be that person, but that's not to say I'm jealous of him. I wouldn't handle having an active imagination such as his. That is mentally too much for my brain. So yes, likewise, I wanted to be an artist at some point, even a Graphic Designer too, but that's before I knew more about the graphic design job. I once wanted to be a Comic Book artist and I still believe it is possible all thanks to Mark Crilley, an artist I look up to despite not being one myself.
And if they don't think you're special anymore once that new child comes, then I think there's an opportunity for you around that time. You should find a way to fulfill the need to feel special for yourself rather than your Mom or Dad. There is no need to rebel against them, just do what you can for yourself. Let the rest of the time in your life be for yourself and yourself only, and only be there for anyone else when they need you. Otherwise, time is on your side. Your sister has become nothing more than an ordinary person to them from what I'm reading. It will also be two more years for me and a few more years for you until you and I become the same.
When that happens you will be on your own. And I can't wait to be ordinary myself; there wouldn't be any need for me to be judged anymore so that I can do what I want within reason. The person I mentioned at the beginning of this post was a hardcore perfectionist who then had a bad case of clinical depression.
So in a nutshell just worry about yourself and your wants and needs. I think I repeated what Brax4 said, but still it was nice relating to you.
Oh and one last thing, be wise
. Do not submit to reality as the way it is, and don't waste your 20s!
