I suppose you could try looking for a new place, but seeing as you are just 4 months in I would try to make your situation work first.
My advice is to try to take advantage of this situation where you are working with people who are smarter or at least more experienced than you. This is a great opportunity to learn, except that it seems you are with people who may not be willing to teach you? But I think you just have to try to find a way to connect with them and show them that you are interested in learning.
It's scary but if they are talking about something you don't understand, make sure that you ask questions. You should be careful not to divert the conversation too much but it's important that you show them you want to learn, and that you realize you have stuff to learn from them. Most people actually do enjoy teaching others, or at least that's been my experience.
In the end you should just not try to stress too much in my opinion. After all, it's just a job! I certainly hope you are "burying yourself in intense study" because you want to learn and not because you are afraid of not doing well in your job. Your lack of success in your job isn't only your own fault, it's also up to the company to make sure you have the resources you need.
Do you have a manager you can talk to about these issues? He/she may be able to help you navigate the team better. It sounds like you are working at a big company so there may well be some programs to get you a mentor too.
