Do we trust God?

I've been thinking lately about how unhappy we can be with ourselves: I can't do this very well, I am not very good at that, why do I look this way. We are not happy with our gifts, we wish that we were more talented like somebody else. We wish that we didn't have to struggle with something that we are going through. Well guess what? God made us who we are and He didn't mess up. He gave us the amount of gifts we have in the areas that He chose to. He created us to look like we do. Now I believe that we should always try to better ourselves, but we should still be grateful with what we were given. God made us in that special way(His image). He made us because we have a special combination of trials, gifts, personality and life experiences to accomplish what He made us for. Think about it. You are not a loser. God didn't make any losers. If He did, then we have a loser God and I am sure not going to go there. I'll leave you with a Psalm that highlights this fact. Especially the bolded parts.
Psalm 139 NASB
1 O LORD, You have searched me and known me.
2 You know when I sit down and when I rise up; You understand my thought from afar.
3 You scrutinize my path and my lying down, And are intimately acquainted with all my ways.
4 Even before there is a word on my tongue, Behold, O LORD, You know it all.
5 You have enclosed me behind and before, And laid Your hand upon me.
6 Such knowledge is too wonderful for me; It is too high, I cannot attain to it.
7 Where can I go from Your Spirit? Or where can I flee from Your presence?
8 If I ascend to heaven, You are there; If I make my bed in Sheol, behold, You are there.
9 If I take the wings of the dawn, If I dwell in the remotest part of the sea,
10 Even there Your hand will lead me, And Your right hand will lay hold of me.
11 If I say, "Surely the darkness will overwhelm me, And the light around me will be night,"
12 Even the darkness is not dark to You, And the night is as bright as the day, Darkness and light are alike to You.
13 For You formed my inward parts; You wove me in my mother's womb.
14 I will give thanks to You, for I am fearfully and wonderfully made;
Wonderful are Your works, And my soul knows it very well.
15 My frame was not hidden from You, When I was made in secret, And skillfully wrought in the depths of the earth;
16 Your eyes have seen my unformed substance; And in Your book were all written
The days that were ordained for me, When as yet there was not one of them.
17 How precious also are Your thoughts to me, O God! How vast is the sum of them!
18 If I should count them, they would outnumber the sand When I awake, I am still with You.
19 O that You would slay the wicked, O God; Depart from me, therefore, men of bloodshed.
20 For they speak against You wickedly, And Your enemies take Your name in vain.
21 Do I not hate those who hate You, O LORD? And do I not loathe those who rise up against You?
22 I hate them with the utmost hatred; They have become my enemies.
23 Search me, O God, and know my heart; Try me and know my anxious thoughts;
24 And see if there be any hurtful way in me, And lead me in the everlasting way.
