Given that the Riemann function defined on the interval $\left[0,1\right]$ is: $R\left(x\right)=\left\{\begin{array}{l}{\frac{1}{q}, \text{when } x=\frac{p}{q} \text{(p, q are positive integers, } \frac{p}{q} \text{ is a reduced proper fraction)}}\\{0, \text{when } x=0,1, \text{or irrational numbers in the interval } (0,1)}\end{array}\right.$, and the function $f\left(x\right)$ is an odd function defined on $R$ with the property that for any $x$ we have $f\left(2-x\right)+f\left(x\right)=0$, and $f\left(x\right)=R\left(x\right)$ when $x\in \left[0,1\right]$, find the value of $f\left(-\frac{7}{5}\right)-f\left(\frac{\sqrt{2}}{3}\right)$.
