The pain you’re experiencing is a blessing from the Almighty. Pain teaches you how to focus and concentrate on your acts of worship. Pain teaches you how to ask the Almighty with a pure heart. So don't complain about it.
When people hurt you as they often do, don't take that hurt and confide in others. Use it to get closer to the Almighty. Confide in Him. Let Him heal you and deal with them.
Whatever happens, even when all your plans fail and all doors seem shut, cry out to the Almighty, the All-Knowing, seek refuge in the Him. He'll find a way out for you. Trust Him.
