Some recommendations of what to do when you are unable to participate in the Sacrifice of the Holy Mass. 
#1. Pray individually or pray with a small group (less than 10)
Begin with the Sign of the Cross
Pray the Act of Contrition
Read the Mass readings for the day (You can find the readings at  in the "Bible" menu)
Spend a few minutes reflecting on the Word of God
Share some prayer intentions
Pray the Lord’s Prayer, a Hail Mary and a Glory Be
Pray a spiritual communion prayers. For example:
My Jesus, I believe that You are present in the Most Holy Sacrament.
I love You above all things, and I desire to receive You into my soul.
Since I cannot at this moment receive You in the Holy Eucharist, 
come at least spiritually into my soul.
I embrace You as if You were already there and I unite myself completely to You.
Lord Jesus, I ask you to never permit me to be separated from You.  
Thank Jesus for this time of prayer.
Close with the Sign of the Cross.
#2. Watch a televised Mass
