Hey geminiswede welcome here to the forum!
I am the same height as you are and I can totally relate to the "scary" number. I chose my goalweight by BMI and was really frightened when I saw: Oh have to be 150 lbs for this BMI
I have never been this light in my entire adult life.
But we can do it!
As we are the same height and have about the same goal, maybe you would like to be weightloss buddies? I find it tremendously helpful to have someone to talk to, who is going to the same stuff you do.
Also congrats on your wedding!

I hope you have a wonderful day!
