My friend, investments also can be an addiction. I used to have a friend that share your same forex adiction. I started gambling because of the same reason as you: a second source of income. Unfortunately few people succeed in trading and all that stuff.
I have investments but in a safer way. (I did not take the investment decitions and someone else does it for me).
I identify with you in many situations: I also owe money and I am working hard to recover it but it will take a couple of years.
Dont give up and lets continue fighting for this!
