I can’t imagine any teacher will let you read an LOR. Those require confidentiality - and rightfully so.
This is such a non-issue - you should really leave it alone and you should not put your teachers in the uncomfortable position of discussing what they wrote about you.
You should be thankful they volunteered to write for you - but the contents are and should be 100% off limits.
Go to class, keep working hard, and apologize to your teachers for putting them in that position. You should never have raised it and you should let them know - it’s a learning opportunity for you and thank them again for their graciousness of writing on your behalf.
Just leave it alone and don’t think of it again.
Assuming the letters spoke positively about you, this will have zero impact on your admission chances.
