To Brother Xavier:
My wife was Roman Catholic/Protestant (RC as baby, then raised protestant, then went back to the RC) and now is Orthodox. Obviously it wasn't difficult at all for her, as semi-liturgical protestant to go to the RC because the feel is so similar, but going to an Eastern Liiturgy has been a process of major adapation for her and she's been Orthodox for some 5 years now. There is still a small part of her that feels like when you put on that old trusty shoe that you've broke in so well that she feels when she goes to an RC Mass, but she knows where the Church is and more and more she feels at home in the Eastern Mass. I should also mention that she felt that same calming "ahhhhhhhh" feeling when she went to a Western Orthodox Liturgy which is quite different from a Roman Catholic NO Mass because... she's western.
All that said, she does feel most at home at our parish. Despite the fact that the DL hasn't culturally 'clicked' with her 100%, she can't imagine going to another parish at this time in her life. SHe used to say that if a Western Rite Orthodox parish started nearby, she would want us to change to that, but now she doesn't feel that way at all.
So, I guess my point is that I won't promise you that after a year of going to the Divine Liturgy it will all click liturgically speaking. It may take years. You may ALWAYS feel that "ahhhhh" feeling to some extent when you go to a Catholic Mass for some friend's baptism or wedding or whatever. And it might click with you very quickly and you may find, as I did, that after a liturgical year or so, the old Mass (or in my case, Liturgical Lutheran Service) doesn't click anymore at all and when you go to DL, you feel that "ahhhhh" feeling

Who knows. If it's a struggle for you, God will bear that struggle with you and will give you reassurance of where you are in other, deeper ways.
Regardless of how easy or hard this particular aspect of the journey will be for you, the Divine Liturgy (Eastern or Western Rite) WILL click for you over time... maybe never completely feelings-wise, but it will click in ways that matter more than that coveted old-shoe feeling

It will continue to click in the ways that matter.
Hope that made SOME sense

PS: about the sarcastic retort people you met.... my GUESS is that most of those people were converts (like ME!). If you convert... just don't be like them. It's an easy trap to fall into!
