1- Train yourself to fully trust Allah. He is managing the entire universe. He knows what He is doing. Every atom knows what to do and how to spin. Trust God’s wisdom.
2- Don’t think of the future. Leave the future to Him. Fulfill your responsibilities today and don’t think of the future. Allah decides the future. Ask him to grant you the best future.
3- Do sujud for several minutes each night and with a deep breath each time say: سبحان ربي الاعلى وبحمده (subhana rabbial a3la wa be7amdeh)
4- Before sleeping, say 100 times لا اله الا الله (la ilaha illa allah) and take a deep breath each time
5- After the morning prayer, but your hand on your heart and say 70 times يا فتاح (ya fatta7)
