I have a few questions to atheists, before I become one.

[Clueless Morgan]

If I somehow manage to answer this, I will be able to live a normal life again.

Hooo-boy, don't sink all your hopes of a normal life into answering a question nobody has been able to answer definitively in the history of humanity. That's the surest way to fail.

I decided to read some atheist forums, watch The Amazing Atheist and some other youtube atheists, and I started to understand how delusional I was. But every time I read or watch a video explaining why atheism is true, I somehow forget all the things I have read and continue to do all the silly rituals, in order to please God, simply because I'm not sure if he exists or not.

Is this a symptom of you trying to please a god, or a symptom of your OCD?

I just want to ask-How can I be sure, or at least not worry about almost all the time, that there is no God?

No one will ever be 100% sure that there is no God. All you can do is evaluate the evidence to the best of your ability and determine the most probable explanation.

Can you tell me how are you sure and living your lives without always trying to figure out if you are wrong about God, trying to argue with yourself all the time, because that's what I am doing right now.

I'm not sure that there is no god. I think it's the most reasonable conclusion given the evidence we have to examine, but all that means is that I think it's way more probable that no gods exist than that a god exists that wants me to love it, worship it, that it needs my money and will send me to hell for eating shellfish.

Every time when I ask the question:Is God real, i end up trying to remember all the things I have read and watched, and if I don't manage to, things get really bad. Please help me, because I am desperate. Please help me get my life again.

I would reiterate what Tonus said: it sounds like you need to get with your psychiatrist and work on managing your OCD and trying to determine if your OCD is really a result of a god belief, or if your god belief is a symptom of your OCD.

P.Slease don't post some comments like: "Yeah you are crazy" or "Yep you are totally restarted and delusional, grow up", because that won't help me at all. Just help me figure this thing out, so I can continue enjoy my life, without wondering if I am doing anything wrong and if I will get an eternal life in a full with fires and torture place.

The thing is we can't really help you figure this thing out, it's something everyone has to do for themselves. We can answer questions, we can give you resources to look into, but we can't make you stop believing in God. Atheism isn't a club you join, it's more like what happens when you drop out of the club you're already in.

P.P.S:I know my English ain't perfect, striving to get better and better at it.

You're doing really well with your English.

I think that I may have not explained correctly - not that my OCD affects my ability to research and work through such issues, it's that I am sure that it is created by the question-"Does God exists?" and the inability to answer it. That's why I am washing my hands all the time, that's why I am making all the other rituals which are considered symptoms of OCD - because I don't know if God exists, so I do them simply because I don't want to risk. That's why I believe that the OCD will be gone when I manage to answer my question.

Once again, I will reiterate that you should really try to not sink all your hopes for overcoming your OCD in disproving the existence of God. That's an unattainable goal. Get with your psychologist and work with them on finding the root of your symptoms and set smaller goals that are achievable and work up to the big ones.
