I beat myself up every day over this investment. I think of myself as someone that has more sense than anyone would be led to believe by my investing in this. I don't fall for much, so how could I have been so wrong? I am so dissappointed in myself. This has been the biggest investment mistake of my life. I absolutely hate that I got family into this. I truly feel like a fool and that is a terrible feeling.
