the time wasted is gone wont come back so don't waste anymore time on it
It’s okay, you can’t go back to fix things. You were stressed at that time that’s why it happened. Now when you have started feeling good about yourself then you should try to regulate your emotions now and focus more on your present.
It is okay, you didn't know about what was happening to you now that you what it is you can get over it, all you need to do is to keep yourself in right place believe me, you can make it okay
