Any “No Sabo” kids become fluent/ improved their Spanish?

Hey Reddit, I’m a “no sabo” kid when it comes to Spanish, and I’m looking for advice on how to improve. My boyfriend’s family mostly speaks Spanish, and I feel really embarrassed trying to speak with them. The language barrier makes it hard to connect with them and have genuine conversations, which is frustrating because I know I’d be able to bond with them more if I could communicate better. I’m determined to get better and gain confidence in speaking, but I’m not sure where to start. Does anyone have any tips, resources, or methods that helped them learn Spanish or overcome the language barrier with family? I’d really appreciate any advice!
