Should I worry because I don't have Publications Yet? Publish...Publish, I am worried about publications as I don't have any yet, I just have few in masters, but was not a good quality, now in Ph.D., I am working on a new topic and to get a significant and validated results it takes times, I focused on developing a model that could really explain the phenomena which are not explained yet by any researchers.

However, as I am apart of the project, all other members are getting papers so fast and every meeting they mention, how their methods are great, I feel low and less confident, maybe I am stupid as I take time.

According to the current situation, I didn't do any success which I think my career in academia is impossible, as I see all successful researchers have tons and tons of citations.

I don't know if I should give up, I bring this to my supervisor, however, he does not care so much, he is not recognized in the field, so it is not a big deal.

I am serious, feel low and lost because of the high competition and I did not have even one good paper yet.

Should I wait or withdraw from Ph.D., I really like research and my topic, what you recommend me to do in that case?

P.S. I am also getting psychotherapy as I am suffering from terrible OCD because of the past experience, I am doing my utter best and fight, but no one knows that in my lab. I am also so ambitious and hard worker, but not intelligent enough as peers that's why I am asking whether I am wasting time in the wrong direction maybe.
Until your supervisor starts worrying, I wouldn't start worrying. Pure paper count isn't the best measure because some topics yield more papers and others much less. For example 2018 Nobel Laureate in Physiology &amp; Medicine, James Allison, has a h-index of 127. Meanwhile 2018 Nobel Laureate in Economics Paul Romer has a h-index of 49. This doesn't mean James Allison is 3x more accomplished than Paul Romer; it just means they're from different fields. In the same way even if your labmate has published 3 papers and you have zero, it doesn't mean they're 3x as capable as you.

Your supervisor knows what is expected of a PhD student at your university. If you are performing badly, he/she will let you know (or it will come up during a performance review). Until that happens, it's not time to start worrying. 

If you are really concerned, you can ask your supervisor if you're making expected progress, or ask him/her to set some targets for you to strive for.
