Breaking Out In Red Spots On Neck And Face!!

Hello everyone, I knew that I wasn`t the only one b/c I`ve seen it happen to other people before on Judge Judy before. I could never go on her show b/c she would ask me what in the hell is all over your neck and face? Sometimes it feels like it is creeping up my neck on my face and it`s going to eat my head. I do it all the time when I am nervous, excited, in the sun, mad, watching a freakin emotional movie! Do I have to live this way for the rest of my life? When I drink alcohol I can feel the heat and I know It`s there, so I have to excuse myself to the bathroom to look in the mirror and OMG It`s so embarrasing to have to walk back out to your friends when you know you are so red! It`s ruining my life. I wonder if my daughter will have it. I used to tan all the time, even bought a tanning bed b/c It masked it a little, but I don`t want to ruin my skin. I can`t tan all year. I have to wear shirts that cover my chest if I know that I am going to be nervous, or even be around other people. I feel like I should be in the circus, and people could pay some money walk in where I am, and bam one minute she`s normal, the next she`s freakin blood red spots all over. It`s retarded. Does anybody have any advice for me???
