Anxiety?

I think I might have some sort of anxiety. I know I've had panic attacks before, and I know what sets them off, but I don't know if I should tell my mom. I feel like she'll brush them off as nothing.

Usually my panic attacks are triggered by someone yelling/getting angry with me. My bio dad is alcoholic and gets angry when drunk. That usually resulted in violent fights with my stepmom. Whenever anyone gets mad at me I start choking up and freaking out and crying and have to use a rubber band or something to calm down.

Also, mental illness runs thick in my genes. My sister has depression, bipolar disorder, and other things that I can't remember. My dad has something I've forgotten. My mom's mom is bipolar, and other things that I've also forgotten. My great grandfather killed himself, we never knew why, and my mom said that others had mental illness.

On another note, as a kid I had something close to anxiety where I couldn't talk to people. Not just shy. I would kick and yell and hide. If someone left without me saying I loved them I would cry and cry and cry. (still happens with my mom just not as bad, rubber band.)

But my question is should I talk to my mom about the attacks or keep shut? I don't know if should talk to her about getting therapy again either, please help. Sorry if this sounds pathetic, I know.
