Dear Dhurr, its nice to hear that you are contemplating the idea of re-locating back to Dhaka.
(Btw, you know me but is still to give me your identity)!!
Sorry i would have replied to this thread earlier if i have noticed. Yes, i think i'd be in a better position to answer your questions since i've gone through the whole phase, and somewhat, is still going.
A lot been answered already, but the most comforting part of your whole moving back thing is that you seem to have a good understanding about what you are about to face.
Sorry i'm running a little low on writing a big post here, because a bit tired now, but i'd update you from time to time.
Verily, in the remembrance of Allah do hearts find rest [Al-Qur'an,13:28]
