bke, it is extremely difficult to suggest unless and until, what is your exact situation. If you are pretty young and you don't have any family problems and you feel I can struggle here for some year, definately you can try another chance but if you have other restrictions, then the situation might be worse. Depends on what you want to do, but if you feel you will search job while studying without OPT is not easy job, as I am on OPT now but because of also some family reason, I am trying to do PhD.
