I think this Tehillim is also appropriate for today..
http://www.chabad.org/library/bible_cdo/aid/16360Tehillim - Psalms - Chapter 1391. For the conductor. Of David, a song. O Lord, You have searched me out and You know. א.
2. You know my sitting and my rising; You understand how to attach me from afar. ב.
3. My going about and my lying down You encompassed, and You are accustomed to all my ways. ג.
4. For there is no word on my tongue; behold, O Lord, You know it all. ד.
5. From the rear and the front You encompassed me, and You placed Your pressure upon me. ה.
6. Knowledge is hidden from me; it is hard, I cannot attain it. ו.
7. Where shall I go from Your spirit, and where shall I flee from Your presence? ז.
8. If I ascend to the heavens, there You are, and if I make my bed in the grave, behold, You are there. ח.
9. [If] I take up the wings of dawn, [if] I dwell at the end of the west, ט.
10. There too, Your hand will lead me, and Your right hand will grasp me. י.
11. I said, "Darkness will darken me, and the night will be dark about me." יא.
12. Even darkness will not obscure [anything] from You, and the night will light up like day; as darkness so is the light. יב.
13. For You created my reigns, You covered me in my mother's womb. יג.
14. I shall thank You for in an awesome, wondrous way I was fashioned; Your works are wondrous, and my soul knows it very well. יד.
15. My essence was not hidden from You, when I was made in secret, I was formed in the lowest parts of the earth. טו.
16. Your eyes saw my unformed body, and on Your book they were all written; days have been formed and one of them is His. טז.
17. And to me, how dear are Your friends, O Lord! How great is their sum! יז.
18. I shall count them; they are more numerous than sand; I have come to the end, and I am still with You. יח.
19. If only You would slay the wicked, O God, and men of blood, "Turn away from me." יט.
20. Who mention You with wicked thought; Your enemies took it up in vain. כ.
21. Did I not hate Your enemies, O Lord? With those who rise up against You, I quarrel. כא.
22. I hate them with utmost hatred; they have become my enemies. כב.
23. Search me out, O God, and know my heart; test me and know my thoughts. כג.
24. And see whether there is any vexatious way about me, and lead me in the way of the world.
