Hi Anne, I have re-commenced attending Mass on my own and had done through a 17 year marriage on my own (despite my side of the family being Catholic), in all probability, the fact I prefer to concentrate praying before the Mass begins and concentrate on all of the Readings, what scriptures Father delivers and wishing fellow Parishioners around me the Sign of Peace. Not judging, however I do notice that some people when in company do not appear to listen or concentrate as much on Jesus scriptures as much as some people on their own anyway.
However, having said this, I love seeing families (particularly young families with their children) when they walk in and settle down instilling attendance at Mass and Jesus scriptures in their children as a family unit. That is something I had growing up with Mum, Dad and my Siblings and treasured to this day.
I count my blessings and thank God, The Holy Spirit, Jesus and Our Lady Mary for those blessings experienced growing up when I temporarily felt sad as a married mother that my ex-husband would not attend Mass of a Sunday with the children and myself.
I looked at the blessings God gave me in my Family growing up.
I know exactly how you are feeling and a little suggestion would be for you to offer to become an active member of your Church and do some Readings, put flowers in the Church, offer to take up the Offertory Procession Gifts from time to time, clean the Church on Roster or hand out the Mass sheets every 3rd Mass, to meet some of the other Church members on Roster.
My sister has done this in her Parish for many years despite working long hours and through her low key involvement, has met so many regular beautiful Parishioners of whom she is still friends with today.
Love and best wishes Anne
