Worried about wedding dress

I just felt the need to vent bc i have been worried about it for weeks now.
i went dress shopping with my mom, sister, and 2 best friends. i felt really overwhelmed while trying on dresses. i liked everything i was trying on and it was very confusing for me.
the dresses i thought i liked everyone else didn’t love. Long story short i chose a dress that i thought i loved and so did everyone else and now i’m having big time regrets. i am a bigger bride so the only thing i wanted to make sure of was my dress was able to have sleeves added. when i went back to try my dress to bring it home i inquired about sleeves and the consultant said she was unsure if i was able to add sleeves due to the 2 different fabrics of the dress. i was so upset. i am very insecure about my arms and the only thing i wanted to make sure of is that they were covered. i did go to a seamstress she actually designs her own gowns and she said it was possible but i would have to get in contact with who made the dress and try to get some of the same fabric that is on the back... she said she can do it but it’s going to take a lot of time and also money 😫this is just turning into a whole big thing now and with Covid-19 we are unable to even contact the company that makes the dress. i am also worried that the added sleeves will make the dress look weird since i was thinking i was going to be adding satin sleeves and that is not possible.... uhg
