Weight Loss - little difference

Since January I have been trying to loose some weight and I am now at 12 stone 4, coming down from 14 stone
However not only am I stuck at a plateau, I don’t feel I look any different. I don’t have a before photo. I am struggling to shift any fat.
For exercise I walk around 15k steps daily at a brisk pace and go cycling. However my fitness levels feel worse than ever.
Any tips?
And reluctantly here is a current photo at 12.4…I am also 6 foot 1
