"Bu vakte kadar kendimle ettiğim savaşları bir ben bilirim"

Thanks in advance to whoever helps me with this.  

Only I know the fights I have fought against myself untill now.

Thank you a lot gokuyum.
I have another question. Does "Zoru sevmek güzeldir" mean tough love is beautiful? Or to love by force is beautiful? 

& this:
"Sen olup başkasından olmayan, işte benim için bu."

It means: It is beautiful to love the tough.

I dont understand the second sentence. It doesnt make sense. So I cant translate it.
