At least there is a Catholic Church nearby- it may be small, but it’s a start into perhaps a new chapter of your life, if you’re willing to find out. In all experiences of our lives no matter what it is, God is always with us; there is nothing to be anxious about, if we let Him guide us. Although easier said than done, when we do recognize His presence presently with us, likely you will experience peace and less anxiety (especially since fear, anxiety, doubt, negativity~ aren’t from God anyways). You may want to search via Internet the Catholic diocese (church parishes) within the UK [I googled that & found 22 dioceses of Catholic churches located in UK- so you’ve got many to choose from to explore your search, depending on how far you’re willing to travel].
Your need for more inspiration is understandable and perhaps you are looking for inspiration that you can relate to. I’m sorry I don’t know what type of inspiration may influence you the most, but God knows; trust Him in everything. For starters, focus on your faith journey rather than what your family may think. If you decide to become Catholic, it is your decision for your life; not theirs. The Holy Spirit seems to be calling you to something more outside of the Church of England, and all you can do is follow, pray, live in the moment, and see what happens.
Anyone who isn’t Catholic is not required to attend Mass every Sunday, because they’re simply not Catholic. Anyone who does decide to attend the Mass at a Catholic Church will receive a blessing by the priest- this happens when Catholics walk in line during “Communion” (to receive the Eucharist) toward the priest… in that case, you simply cover your chest with your arms [right arm crossing upward toward left shoulder & left arm crossing upward toward right shoulder- the standard way to know one isn’t Catholic to then receive a blessing]. Most Catholics don’t have a ‘very strict Christian lifestyle’- being Catholic is not as bad as people make it to be.
If you decide to become Catholic by joining RCIA (that’s the process to become Catholic), here are some aspects to keep in mind:
~We are human just like everyone else. We sin, make mistakes, etc. that everyone else does too. But we have the Sacrament of Confession (also known as Reconciliation) to confess our sins & mistakes to a priest for our souls to be rejuvenated and aligned toward pleasing God with our lives. Being obedient (open-mindedly) to attend Mass every Sunday as Catholics is not a bad thing… typically those that desire disobedience from God have something selfishly to hide within their lives that has something to do with submitting one’s will with higher authority (God), rather than attending church itself; an excuse. It is one’s soul that is at stake, if the Catholic person decides to not attend Mass every Sunday… that’s between the person and God. ~all I can do is pray for them.
In terms of the ‘very strict Christian lifestyle’- the answer is no. That strict Christian lifestyle is typically for those discerning a (catholic) religious Vocation to the priesthood, religious life (males: to be priests, brothers, or friars. females: to be nuns or sisters). As long as you accept and follow the Catholic Church’s teachings (attend Mass every Sunday & holy days of obligation [usually feast days of Mary & Saints- those are to honor the Saints & Mary as the Mother of God]), go to Confession (at least once a month~ again, not all Catholics do this for different reasons, but most do), pray, & strive to love and serve others the way Christ has done for us is highly recommended. Keep in mind, though that everyone is different & unique. Meaning that God speaks to us differently… although God is calling me to interpret the Catholic Mass to deaf people to serve Him with that ability, God may be calling you to touch others’ lives (even your family) in ways that only you can do (with Him) with what abilities He has given you, for the purpose to give Him glory and build His Kingdom here on earth- to ‘bring all souls to Heaven.’
You aren’t expected to “go away & do lots of studying”- that is part of discerning a religious Vocation (except the ‘go away’ is more like spending quiet time w/ God in silence and in community to pray & contemplate & the 'do lots of studying is more like visiting religious communities or doing schooling for priesthood to study the way of life), if one is called to that. There are multiple resources, references, and ways to live a virtuously Catholic lifestyle without the strictness that you seem to be focusing more on… Catholicism is much more enriching than that and the more you dive deeper into exploration, the more you will understand what I mean.
There’s no need to get involved ‘heavily’ with all church activities. Do what works for you, what you enjoy doing, & what God may be calling you to do thru prayer. There’s nothing wrong with getting involved at church (it’s a great way to grow spiritually [whether thru cantoring, joining the choir, being a lecturer, being a Eucharistic Minister- not a priest but a lay person who assists within Communion, servers, greeters, etc.- God made us diverse to come together and celebrate the Mass like pieces of a puzzle to form an image & likeness of Him.
