Should i get medication/other treatment for anxiety?

For 4 years or so i was depressed. I wasn't officially diagnosed but my doctor knew it, we just didnt speak about the subject because I was a minor at that time and I didn't want to deal with my family, so she respected my privacy. A while after I recovered from that I started developing anxiety problems, but I again sucked up because i didnt want to deal with my family. I also experience pretty bad social anxiety.
The problem is that it's increasingly becoming a physical affliction, something I can't control by being positive or some crap. Its a bodily reaction with a mind of its own, like someone is prodding my brain and my organs, especially my stomach, with a sharp stick and shaking nerves around. I'm getting better at hiding it, but at the same time it's happening more often and sometimes preventing me from behaving normally. When i go out of the house and people talk to me, my brain shuts off, as if my IQ dropped to the level of an incoherent moron, and I can't think of answers to basic questions. Basically going anywhere and doing anything makes me feel sick, but most times i can contain it. It's pretty obvious to the people around me that I have a problem though. Exams? it's hard to pass when you eyesight is blocked by tears. Public speaking or speaking to any group thats more than 3 people? lol forget it.
The reason I'm asking now is because I'll be out on my own soon, and I worry if I'll be able to handle it with this level of anxiety. I'm going for a physical soon, which i rarely do, so I'm trying to decide if i should mention it to the doctor. Should I?

Just to clarify I only have actual panic attacks when provoked by external forces, aka assholes, but I would probably classify my problem as closer to moderate than mild.
