I'm sorry you're having a bad day. If you wanted, you could post your vent as a blog on your spark page. You could then set your page to "private". that would only allow your spark friends to view the blog. Does your family know that you spark ? If they have no idea you're here, I'd say blog. Then if you'd like opinions or advice, post a link to your blog. I think you'll find the spark community is helpful as well as supportive.
Not knowing the situation, I will give you one piece of advice a friend of mine gives me. "Why do you care what other people think ?" The reason these people are upsetting you is because you're allowing them too. Whatever comments they're making, you need to shrug them off and turn the other cheek. I know that's not easy, but the more you let the comments bother you, the worse you'll feel. I know what it's like to have family criticisms.
