Re: Any USCG members here?
I'm a coastie... I worked at Recruiting Command for a while, and was talking to one of my buddy's who is a recruiter. It's tough right now, some areas have a year+ wait-list (white males) it's a little easier for women and males other than white, but not much. Our budget was just cut pretty dramatically. We lost something like 900 jobs, and have reintegrated those people elsewhere into the fleet taking jobs that would have been recruited for. I think there's going to be more pain in the future. This is probably why you were DQ'd for something that is generally waiver-able. If you are dead set on becoming a Coastie, write a letter to you congressman or senator (both); include something from a doctor that says you have not had any trouble since you were a child. These letters usually do the trick if there is any chance at all.
By the way I recommend enlisting and applying for OCS from there, I spent eight years as an enlisted guy and loved it. I've been an officer for almost five years now, and the enlisted time is invaluable.
If the congressional doesn't work, and you still want to serve, go to the other recruiters. It's funny I joined the CG because I liked the idea of LE and driving boats, and I ended up in Iraq. But my experience over there had a pretty dramatic effect on my life, has made me a better leader, and shown me what hard work really is. Point being is I believe a deployment to somewhere like Iraq or Afghanistan can help develop/hone your leadership skills and provide you a true understanding of how you perform under "real" pressure. To gain that experience it doesn't matter what color the uniform is, all that matters is your character and how much you apply yourself.
Good luck, shoot me a PM if you would like to discuss further.
