If you’re not confident, and unprepared, of course it’s going to be difficult to witness.
However, 1857 For a sin to be mortal, three conditions must together be met: “Mortal sin is sin whose object is grave matter and which is also committed with full knowledge and deliberate consent.”[131]
1862 One commits venial sin when, in a less serious matter, he does not observe the standard prescribed by the moral law, or when he disobeys the moral law in a grave matter, but without full knowledge or without complete consent.

You weren’t sinning against the moral law or any grave sin…it was more a weakness I would think, along with a lack of information.
As it is, you’re not yet Catholic and have still much to learn, I’m sure.
And yes, it’s hard to interact confidently when you’re shy.
You do have some responsibility to get to know the answers to these things.
We are required to witness as Jesus said after the resurrection and before the ascension. We do have a responsibility to read and know the gospels, the New Testament, and then, the Catechism of the Catholic Church…both of which are available in full online.
For instance, you can witness from the gospel regarding Mary as intercessor.
At the Wedding feast of Cana, ( John 1:1-12) Mary made a polite and slightly indirect request of Jesus to save face for the hosts. The event was almost out of wine.
Jesus replied basically that it wasn’t time for signs and whatever, but Mary quietly told the servants to do whatever He asked them to…she trusted He would heed her request, her intercession for the hosts. And He did, even though it wasn’t yet the time for miracles.
You see He overrode that objection to answer her courteous and respectful prayer/plea as she drew His attention to the problem.
You can’t go better than the bible for demonstrating truths to our Protestant brothers and sisters!
If Jesus objected to Mary’s intercession He’d have said, 'absolutely not!", but no, He gave into her untimely request…because He loves His mother so much!
You have a sincere heart it is evident, and hopefully, with time, you will have the courage you wish to witness.
Jesus apostles didn’t do very well in witnessing until after the Holy Spirit came following the Jesus’ ascention into heaven. Later they did brilliantly and I pray the same for you in your own quiet way. God bless you. And please be at peace.
