Welcome back friend.
Please do not get hurt by some stupid people who do not like others to proceed. Do not mind them and continue your work. Those who hurt you deliberately, leave them to God, He is the one who will look after them.
Look at the history, so many great.. great people were also criticised by the people of the society.This will happen in every walk of your life.. no matter how good you are. It is easy to say but difficult to practice, so don't worry and be happy.
I remember one qoute here " What if God stopped loving and caring for us because we failed to love and care for others?"
Next one " Do you love your creator(God), love your fellow creature first"
You have shown in your posts that you love and care for us.
God bless you Bro.
