How do I know if I'm bad at writing?

I've been writing for as long as I can remember. I wrote fan fiction for years and when I was in high school I decided to start writing original fiction. I had no problem getting the ideas, and I thought I was pretty good at it. But then I started sharing my work with people, and I am baffled by the response I get.<br><br>They don't like it. They don't like my writing style, or the characters, or really anything. I can't even get my parents to finish the first chapter of anything I've written. They always say that I'm a good writer, but they don't like the subject matter. I've tried writing different things, and it doesn't matter, they don't like it. Even my friends won't read my writing.<br><br>Now, I am aware that writing is subjective. What someone might like, another person might not like. But I am getting a lot of the same criticism over and over again. My physical descriptions of characters are lacking. My world building is nothing special. I don't have a writing style.<br><br>I really don't want to be a writer, I have to be a writer. I have so many ideas that I need to get out. I have characters that I can't ignore. I have worlds that I need to build. I can't function without it, it is my stress relief, my comfort, really my life. But every time I get a bad comment on my writing, I stop. I can't make myself write for weeks or months. I need to know if I'm bad at writing.<br><br>I want to make a career out of writing, but I don't know if I'm good enough. Is there any way to know if I am a bad writer? I know that the only way to get better is to keep writing, but if I suck, why bother? <br><br>Sorry, if I just seem like a pity party. That's not what I'm going for. I just need help.<br><br>EDIT: Thank you, everyone, for the comments and the critiques. You have no idea how much it means to me. I took a lot of what you have said into consideration and you're right. I need to keep writing and grow. I read a lot, and that is going to help with my writing. I'm going to keep asking people to critique my work. I have already started on a few projects, and I can feel a difference. <br><br>I know that I'm not a bad writer. I just need practice. Thank you all so much for your help and support.<br><br>EDIT 2: I have been blown away by the amount of support and help that I have received on this post. I never expected to get this many responses. Again, I want to say thank you to everyone who has commented and reached out to me. This has been a humbling experience, and has made me even more grateful for the writing community.
