You can still be Catholic, even if you can’t make it to Mass. I second asking the priest at the parish if there is a way the parish can help you get to Mass. I would be happy to give a ride to someone.
If you are totally unable to get to Mass, the obligation does not hold. Some reasons for missing Mass are: being sick, caring for someone who is sick and cannot be left alone, helping people who have had an accident on your way to Mass, icey roads or other unsafe weather, having to work, etc.
It is good to set aside some of the day for spiritual reading or other similar activity. For example: watching the Mass on TV, reading the Sunday readings in addition to your normal reading, and that sort of thing.
Many people have been unable to get to Mass. When the English we’re switching over to Anglicanism, Mass for Catholics was very rare. People in many parts of the world are unable to get to Mass because Mass is celebrated in their area only every so many weeks or even months.
