The specific difficulty you are naming, that the success is exactly what makes it unspeakable, is one of the most common things Pakistanis abroad bring to a first session.
A few things worth separating. Loneliness after a move is not a sign that the decision was wrong; it is the ordinary cost of leaving a dense social world for a thinner one, and two years is well within the period where it bites. It also tends to get worse before it gets better, because the first year has novelty in it and the second does not.
The part that does harm is the silence. Not being able to tell your family means you are managing both the loneliness and the performance of being fine, and the performance is usually the more tiring of the two. You do not have to solve that by confessing everything to them; having one place where the performance is not required is often enough to change the weight of it.
Sessions here are online and the practice works with people in other time zones, which for many people abroad matters more than the content: it is a conversation in your own language, about a context that does not need explaining.
This is general information in reply to a public question, not advice about your own situation, and it does not create a client relationship. If you are in immediate danger, contact emergency services.
