Did you every ask the Lord if this investment is what He wanted you to do? And now you want Him to "fix it"? He will turn it around for your good, "when" you fully turn to Him in repentance and prayer and put Him first in your life and the things you do.
Matthew 6:33 (ASV)
33 But seek ye first his kingdom, and his righteousness; and all these things shall be added unto you.
And if He makes things right for you, what will you then do with it?
James 4:1-4 (ASV)
1 Whence come wars and whence come fightings among you? come they not hence, even of your pleasures that war in your members?
2 Ye lust, and have not: ye kill, and covet, and cannot obtain: ye fight and war; ye have not, because ye ask not.
3 Ye ask, and receive not, because ye ask amiss, that ye may spend it in your pleasures.
4 Ye adulteresses, know ye not that the friendship of the world is enmity with God? Whosoever therefore would be a friend of the world maketh himself an enemy of God.
By HIs grace He may pull you out of the situation unscathed and whole. He may not. Will God still be good either way in your eyes and mind? Do you believe and trust that God is good, all the time.
In the name of Jesus, I bless you with the life of God and His wisdom and understanding.
