Whatever is decreed shall not be by-passed or set aside. You will have to endure what Allah has ordered in the 'Loh Mahfuz' for you.
There befalls not any calamity either on the earth or (specifically) on your own persons, but it is recorded in the Book before We bring it into being. Surely that is easy for Allah. (22, Al-Hadid) over what is lost to you.
Note: According to Hazrat Mujadid Alif Sani, the destiny is of two categories: (a) معلق or alterable or suspendable, and (b) مبرم or unalterable. The former has again been divided into the following two varieties:
i) Those which may be suspended due to some unusually corn mendable act on the part of the person concerned, i.e. benediction of parents or malediction of an oppressed person; and
ii) Those dependable solely on Allah's sweet will. They are not swayed by any thing human but yet are alterable.
In the above verse Shah has obviously referred to the unalterable destiny.
(My note on determinism or predestination may be referred to for better appreciation.)

What is recorded in destiny none can escape,
Patiently bear what Beloved has written on your slate.

What is writ on fore-head can not be transferred to back-head,
Keep to all that the beloved has written on the tablet of your fate.
