Time goes on..

If only i shut my mouth.
If only i stopped.
If only...if only..
This is regret..and I've done it so many times.
I know that time is irreversible and you can never return to what has passed...but i think reminding yourself that at a certain time, you could have done something else, that you shouldn't have done what you did, that you knew that it was wrong but you still did it under ignorance, and you just totally regret..isn't wrong..
To regret is to try stop..taubah. and it is important.
I can learn, i can change, but what happens to the person inflicted, can i take back my words?can i heal the pain?
this post can be removed, but what you have read can not.
So what can i do..i donno, just hope that Allah aids me..
