I can assure you that we Eastern Catholics have no problem worshipping with our Orthodox brothers and sisters - whom we consider (know) to be Catholics, albeit not in communion with us. You prayed there to ask God which path He wanted you to take - you can pray anywhere and asking God to assist you in discerning anything is not, can not be, a sin.
You say you were READY to convert - the unsaid conclusion to that sentence is ‘if I understood that God wanted me to do so.’ As you did not do, presumably because you did not discern it to be God’s will for you, you never sinned.
I don’t know how to go to Confession because what if my Confession would be invalid.
Why would your confession be invalid? You are, again, creating a scenario calculated to make your worst fears be reality. If there is a sin here, it is in failing to believe/have faith in God’s mercy and forgiveness - if there is even anything to forgive.
I do have a spiritual director for the scruples but I don’t know if this is scruples or not. Because it’s not in my mind… .it’s in Canon Law
It does involve scruples. You are utilizing an imperfect understanding of Canon Law as a medium against which to measure your actions - doing so is, indeed, a manifestation of scrupulosity. Canon Law is not ‘fact’ but the imperfect (non-dogmatic) attempt of Church leaders to provide a framework within which to function. It is not a rulebook by which the average layperson is intended to life out their spiritual life or those temporal aspects of it upon which spirituality is or ought to be interlaid.
Consider that, until the current times and the ready availability of such textual material on media such as the internet, the average Catholic - Latin or Eastern - was blissfully unaware of most provisions of Canon Law. The number of laypersons who ever saw, let alone read, the 1917 Canons (predeccessor text to the current edition) was miniscule in relation to the body of Catholic faithful. And, in some ways, that was most assuredly for the best - because it avoided the modern day practice of privately applying the Canons to one’s life and using those interpretations to either scare oneself silly or to identify loopholes that excuse one’s actions. In earlier times, the average layperson relied on a Catechism - a document written in style that answered the layperson’s questions about matters of doctrine, praxis, sprituality, etc, in ways that did not leave the individual out there trying to play the role of canon lawyer.
While I applaud the fact that education and literacy are now such that laypersons can be better informed in matters theological of all sorts, it has had the unfortunate effect of producing ranks of pseudo-theologians, pseudo-liturgists, and pseudo-canonists - the vast majority of whom are frightfully unprepared to take up those roles. Witness almost any thread on this site in the Liturgy, Apologetics, Spirituality, and other fora - each replete with a host of individual interpretations to posted queries - diverse, divergent, and in many cases absolutely wrong, yet almost every one of which will be seized upon and believed by some reader.
We are, in effect, developing into a Church where commonality of belief is a thing of the past - it is cafeteria Catholicism at its worst, despite that many of those practicing it would be the first to decry ‘cafeteria Catholicism’ as abhorrent and ranking right up there with the worst heresies of all time.
You need to take a few minutes and read carefully some of the myriad posts that you’ve made here and at other fora and allow yourself to acknowledge how many of them are variations on a theme - arising from self-interpretation and application to yourself of Canons that were not, are not, intended as day-to-day guidelines by which Catholics live their lives. And, you need to accompany that by a realization that everyone cannot be wrong all the time, thus - question asked, question answered, move on - do not revisit the matter with new variations on a theme, to see if a different answer will result.
The totality of the discussion - by the time it ends, which it almost never would, except that respondents grow weary of repeating themselves - most resembles an undergrad course in logic or metaphysics, wherein multiple scenarios are urged on the students to have them understand the variant outcomes which result from each. ‘What if …’ in the effort to test one’s actions against Canon Law can become a self-fulfilling course of destructiveness, compounding the unworthiness of each of us as human beings, until we cannot accept that we will ever achieve even an iota of the goodness that God asks of us - and that cannot be true if we are to believe that God wants us to succeed as spiritual beings.
