I Just Joined This Forum I Think I May Have Anxiety

If anyting remotely out of place happens or I think it will happen I go insane. Not just sick with worry but I get this physical feeling and I can't think straight. I worry sooo much its like I just want to die. The only way I fight is to go to sleep ( with medication). That is just the tip of the iceberg I get feelings like over other things like being in public places around crowds etc. I start to sweat and I feel like I can't breath and my heart is going like a million beats per minute its just sooooo frustrating. These feelings are taking over my life I don't know what to do!
