New with a lot to loose

Hi
I am 44 yr old woman from uk.
Currently on HRT as perimenopausal.
I have yo-yo ed all my life but now at a point where drastic action is needed my health is being impacted. High bp, very bad back, breathless etc.

I am 5ft 1 and 97kg my target is 60kg for now.

So here I am beginning the long road to better myself :)
