Former Arminian, newly Reformed. My story(r/Reformed)
You, my friend, need to read Jamie Smith’s Letters to a Young Calvinist ASAP. It’s a fantastic, short, cheap, pastoral, and easy-to-read book aimed at people exactly like you. Smith himself came to the Reformed tradition from a pentecostal background and does an excellent job of cautioning against various pitfalls many new “converts” encounter.
/u/bobwhiz rightly cautioned against the cage stage. Letters to a Young Calvinist is the best antidote.
