While I obviously do not agree with your conclusions regarding the doctrinal purity of the EO and your reasons for leaving, I would say that Truth is of far greater importance than feeling comfortable. It can be tough initially, but many of us here have done it. If you truly believe that the OO alone are the true Church of Christ, and that the EO are heretics with an invalid Eucharist, then there really is no excuse for you not to join an OO church (although waiting a while to make sure you don't rush into anything is advisable).
Coptic churches tend have great emphasis on involving the youth, who often speak very poor Arabic, and so you often get English Liturgies, English Tasbeha, English Bible studies, etc. even if it's an exclusively Egyptian parish with little focus on wider mission.
