Thankyou very much! Do you know any techniques which I could use to try loosen my jaw and stuff? : o

I recently decided to try out singing properly, and this is my first ever song cover, I would love honest critique and advice and everything! It would help out a lot, I also have some questions which are causing me to kind of lose confidence in my singing however, so the answers would really help: 1) When I first sang this song, I sounded awful, is it normal to sound really bad at singing a song on your first try? 2) It took me awhile to actually sing the song until it didn't sound awful, I started singing this song back in January time. However, I only sang like once or twice a month (if lucky a few times) on average for an hour/half hour, or sometimes never because I only sing when no one is in my house due to shyness. Is it normal to have to spend that long on a song? 3)What is the average amount of time it takes to sing a song decently? I kind of think that because it took me that long to actually sing the song to the level it is now, it's like cheating/doesn't count/ not my actual singing voice if that makes sense Thankyou very much! Much appreciated!
