Hello, my dear friend,
I hope you are doing well, I am also good here.
I write this letter to seek apologies for not being available with you when you needed me the most. I feel sorry for not being in contact with you or reverting to your phone call. I have got stuck somewhere ________ (in Project work/taking care of my hospitalized parents/ others) and due to this I have been extensively busy. I know how it feels when closed once are not in contact and you have no one left to talk to.
Hope you can forgive me.
Let’s catch up soon.
Yours and only yours friend,
_________ (mention your name here)
