Having been a lifelong Episcopalian and a senior warden in Tennessee, I left the church over 6 years ago, when it left me.
Now living in the Philippines, I will obviously attend the Catholic church.
I do not, however, see a reason to actually become a Catholic.
If someone gives me a reason, I would consider it.
You need to formally convert if you wish to receive the Holy Communion or other sacraments if the Catholic Church.
You are, like everyone, welcome to visit Mass and pray, but you cannot receive Communion.
That reason has to come from your heart. I would suggest your read some stories about converts. You might identify with one and the “reason” would virtually jump off the page at you.
A good book to read about the subject
