The story about the thief who was crucified next to Jesus may give a Biblical precedent for your position. The “good thief” alongside Jesus never attended a Christian worship service, but the Lord still promised him salvation. Faith in Jesus as Saviour, not church attendance, saves you.
On the other hand, Scripture is also clear that people who have been cleansed of their sins by the Lord don’t practice their faith in a vacuum. Just as a person in love doesn’t need to be told to spend time with the object of their affection, Christians don’t have to be told to spend time with their Saviour.
You could reply, “I can spend time with Jesus on my own.” Maybe. But Jesus said “For where two or three are gathered in my name, there am I among them.” He calls His people to share the Lord’s Supper (communion) “…often, in remembrance of Me.” Are you doing that? Jesus said we should share His salvation story all around the world. Are you doing that? Christians are to encourage each other and sing praises to our gracious God. Is that happening in your life? While it is theoretically possible to be a Christian without attending worship services, the Bible is consistent in encouraging God’s people to gather together to receive His gifts.

“And let us consider how to stir up one another to love and good works, not neglecting to meet together, as is the habit of some, but encouraging one another, and all the more as you see the Day drawing near” (The Bible, Hebrews 10: 24 – 25).
“And they devoted themselves to the apostles’ teaching and fellowship, to the breaking of bread and the prayers. And awe came upon every soul, and many wonders and signs were being done through the apostles. And all who believed were together and had all things in common….And day by day, attending the temple together and breaking bread in their homes, they received their food with glad and generous hearts, praising God and having favour with all the people. And the Lord added to their number day by day those who were being saved” (The Bible, Acts 2: 42-47).
