Hey Purbita, you do not need to apologise to anyone. If anyone did take your silence as a personal insult, they wouldn't deserve you anyway. I am so sorry to hear what has been happening for you, but also very grateful to know that you think of me as someone in your circle. I care and I want you to be well, not feeling like you have to explain yourself. But I am also grateful for this update and that you are reaching out and sharing some of the struggles you are going through.
Be gentle on yourself and come back when you are ready.
