Hi again, mikeforjesus.
It is bed time and then some here, but I wanted to say a few things.
First, the holy scriptures tell us that sufficient for the day is its own trouble (Matthew 6:34). I point this out because there is a lot of worry about the future in your posts. As you have pointed out, God will fix what He wills. Be still and know that He is God.
Second, of course prayer is good to keep us balanced, but even more than that it is as HH Pope Shenouda III put it in the sermon: it is
taking from God. So if you recognize these problems (lack of balance, worry over your family, etc.), these are things to bring before the Lord in your prayers, because He has all that you need to deal with all of this. Maybe you will not be like Hanna in the temple, but just as in her example it is perseverance in prayer which leads to the kind of saintliness we see in St. Anthony and others.
Also, remember the story of the angel appearing to St. Anthony (at least I think it was him; I am away from my books right now, so I can't check, but it's definitely in the translation of the sayings of the Desert Fathers that I have) where the angel told him that there was man who was his equal in holiness residing in the city. Upon hearing this, St. Anthony went by the angel's direction to see this man and found a simple physician living an anonymous life who went about his work with prayer, gave his money to the poor, and every day chanted the Sanctus with the angels. No doubt there were probably worries and anxieties in this man's life, too (after all, that's part of the human condition, in so far as we become wrapped up in them), but the angel showed St. Anthony and us what was really important to living a balanced spiritual life. It is not so much the absence of problems (not at all, in fact; recall St. John the Little: "Lord, send me enemies, and give me strength for the fight"), but the focus on daily faithfulness in the way the Lord sets before us. Not everyone is called to the desert as St. Anthony or St. Paul the Hermit was. So I don't believe we can or should say that God only wants Orthodoxy revealed by those who are as saintly as St. Anthony. Of course we want to always try to be good representatives of our faith before others, as here on CAF, but there is a bigger lesson to be taken here about trusting in the Lord and honestly just...y'know...maybe slowing down a bit and taking things in an accepting and open fashion (note: NOT indifferent, as some people would have us be for having the temerity to say that Orthodox Christianity is uniquely true, as our faith commands of us, but in the sense of being soft-hearted, as we've talked about). Maybe not everyone is meant to preach to this or that people as in the days of St. Paul before the pagan Greeks, or in the fiery and righteous ways of someone like Iyowannis the Iconoclast in India or my beloved and holy father St. Shenouda the Archimandrite, but certainly you have a place too. We all do.
So why not try instead in situations like you mentioned with the Coptic Catholic future in-laws: do not worry about fights, because you will not cause them (commit yourself to that). Just be a good Orthodox Christian and avoid cross words about anyone. It is hard to get into arguments when you keep to the hours in the Agpeya, for instance, because you will occupy yourself with prayer, which is the best work and the antidote to all worries.

Maybe they will even see what you have as an Orthodox Christian and desire it. Who knows. Either way, again our job is to be loving towards everyone.
