Brother the site you mentioned is a propaganda site that is based on lies and things taken out of context.
The internet is a dangerous place to be learning Islam because there are organisations and religions out there that will do anything to get people to join their "side".
I know people normally feel shy/reluctant to do this but you
need to meet with an Imaam at your local Mosque or meet an Islamic Scholar.
There is nothing better than having your questions answered face to face.
Please stay away from the propaganda sites and if you want to learn about Islam learn it from the main source... the Islamic scriptures. Then there will be no room for lies. For every Muslim that leaves Islam another 1000 come to Islam to replace him.
Like I said Brother you can add me on msn if you need to talk. I am no Scholar but I can at least share with you what I know of Islam.
Brother also although I know it doesn't offer much comfort but I wanted to say that we are all gonna die soon. Some sooner than the others but truth is it could happen tomorrow, today, right now! We just fail to acknowledge the only definite thing in life... death.
Brother please do meet with a good, well educated Imam/Scholar as soon as possible.
Also if you knew the character of our beloved Prophet (peace be upon him)your mind would be at ease and you would ignore the lies people spread about him. Here is a beautiful article about the Prophet (peace be upon him)

Brother as I said I am here for you if you need someone to talk to.
May Allah's peace and blessings be upon you.
Your Brother in Islam.

Edit: Guys can you please cut him some slack? You need to understand how he is feeling right now. Rather than criticising him why not offer some good advice. Please...
