Oh dam, never panic that seems to be the trick, and if you do think healers will attack you often/alot, you can just lure the healers into the Italy rock, and kill them before proceeding with Jad, so you can never lose focus on Jad. Good luck.
Sorry for your loss, but maybe the VPS IP's address is flagged, most VPS are flagged by Jagex just to let you know, it's rather hard at this point to even find a VPS that is not flagged, but by the sound of things it does indicate that you are most likely flagged.
Sorry to break it to you buddy, but you are some 100% something wrong, don't blame OSBOT for getting yourself banned. Go walk it off and come back and kindly explain how it occurred and we might be able to assist you.
There are free resources all over the internet, I don't see really see the point in learning from a member here, but it's better to just use tutorials. If you need any tutorial links drop me a message.
If you don't want to risk your account for a ban then use MouseKeys. Jagex team has said that this is allowed in the game, and most people actually make use of this, myself being one of them. I don't really suggest others as then they can get you banned, and it's against the rules.
I'm actually surprised how serious people are getting, of course I'd trust RoomScape without doubt. I've count countless trades with him, and most likely will do in the future.
