Am I still Catholic? I would like to find out, I was confirmed in my Catholic Church, and used to go often. However as I got older, I could never get to church, as my parents did not wish to take me. I then went overseas for a year, came home and moved to another town. I have not been back to a Catholic Church until this past Sunday.

I want to know, since I have been gone for so long, what can I do to enter the Church properly? I love being Catholic and when asked I let people know that I am Catholic. I want to enter the Church correctly. If someone can please give me guidance.
Yes! You're Catholic.
Quick follow-up question though: did you receive a first Communion when you were younger?  If so, you probably just need to go to Confession before you can get in the Communion line again at Mass.  (That's true of any practicing Catholic who hasn't been in a while.)

If you never received Communion as a child, you may be required to attend an RCIA class ("rite of Christian initiation for adults") to re-learn the faith and get ready for a first Communion.  In most parishes, RCIA starts in the fall and runs through the next Easter, so don't dilly-dally and they will probably be happy to let you join this year's class late.

In either case, go talk to a priest before you take the advice of some guy on the Internet.
