I need help!

I've always been good at keeping my anger in which is surprising since i have anger issues. Anyways I've started to lose control of it. I feel like I'm about to snap. Back then I never talked back and tried to ignore the feeling in me that tells me to let it all out. but now I started clenching my hand into a fist, wanting to break something, kicking the air to kicking bricks that hold my house up, curse and say bad things when no one is looking.

I feel like I could explode with anger right now. In some cases u could say it's just like the song 'Monster' door skillet because I just can't control it as well as I used to, I feel like I have a monster inside of me. i don't want anyone to know about this. How can I control it before it unleashes itself and lets everyone know how I've really felt.

I don't know how to control it anymore. It's like when I grow older my anger starts to grow even more. I really need help on how to stop it from coming out. I don't want to hurt any of their feelings. Please help me!
