Don't be afraid to ask questions, or to meet people. It may take time, but it'll happen.
If you are concerned about language issues, look for a service book, or pamphlets they may have with copies of the briefer services as well. I picked up a lot by reading the Orthros booklets. Also, ask the parish staff for help. If you can't get a guidebook at the parish, there may be some online. Don't think that you have to let yourself be confused- relax, enjoy the services, ask around and someone should be able to help you. The newness may seem daunting at first, but it will be much better with time.
Try to take in a parish event from time to time, whether the coffee hour after church or something else. It will help break the ice, and you can find some new friends.
Read at home, if you have time. Your church may have a lending library. If not, there's the public library, and so on. If you're ready for the catechumenate, your priest may ask you to read some things. There are some excellent materials out there about the lives of the saints, the councils, etc. These will help to open up what you know about the Church, and strengthen your faith.
Don't give up.
