I would suggest reading Ecclesiastes, chapter 3
in the Old Testament. It's not an easy pick me up but it's a faithful person's (the Word of God) genuine and intelligent response to life's ups and downs. In case you don't have access, here it is:
1: For everything there is a season, and a time for every matter under heaven:
2: a time to be born, and a time to die; a time to plant, and a time to pluck up what is planted;
3: a time to kill, and a time to heal; a time to break down, and a time to build up;
4: a time to weep, and a time to laugh; a time to mourn, and a time to dance;
5: a time to cast away stones, and a time to gather stones together; a time to embrace, and a time to refrain from embracing;
6: a time to seek, and a time to lose; a time to keep, and a time to cast away;
7: a time to rend, and a time to sew; a time to keep silence, and a time to speak;
8: a time to love, and a time to hate; a time for war, and a time for peace.
9: What gain has the worker from his toil?
10: I have seen the business that God has given to the sons of men to be busy with.
11: He has made everything beautiful in its time; also he has put eternity into man's mind, yet so that he cannot find out what God has done from the beginning to the end.
12: I know that there is nothing better for them than to be happy and enjoy themselves as long as they live;
13: also that it is God's gift to man that every one should eat and drink and take pleasure in all his toil.
14: I know that whatever God does endures for ever; nothing can be added to it, nor anything taken from it; God has made it so, in order that men should fear before him.
15: That which is, already has been; that which is to be, already has been; and God seeks what has been driven away.
16: Moreover I saw under the sun that in the place of justice, even there was wickedness, and in the place of righteousness, even there was wickedness.
17: I said in my heart, God will judge the righteous and the wicked, for he has appointed a time for every matter, and for every work.
18: I said in my heart with regard to the sons of men that God is testing them to show them that they are but beasts.
19: For the fate of the sons of men and the fate of beasts is the same; as one dies, so dies the other. They all have the same breath, and man has no advantage over the beasts; for all is vanity.
20: All go to one place; all are from the dust, and all turn to dust again.
21: Who knows whether the spirit of man goes upward and the spirit of the beast goes down to the earth?
22: So I saw that there is nothing better than that a man should enjoy his work, for that is his lot; who can bring him to see what will be after him?
Ooops, I just realized it says no religion in this forum. Hope this is o.k., Muhammad
