Is there hope after a DUI?

Dam, I feel like my life is just over. I got my first DUI. I blew a 0.089. I was on my way to go see my son in Utah from California. I thought me and my x-wife were going to get back toghether and then on the way there she basicly said no, don"t bother coming up "it's over." Anyways, I got all bent out of shape over this and drank over it. The next morning after getting a few hours of sleep I continued on my way to Utah still hoping for the best. But while on my long journey I got busted. It's been all hell since then. I just don't know what to do. I feel like my life is over and I'm just hopeless. I don't know how to keep my life afloat. It was already messed up but now I almost feel suicidal,especially after reading about all of the horrible consequences of a DUI. This has just been crap upon crap. I can't afford a lawyer, and I can't afford a conviction, which seems impossiable to avoid. Is there hope in this situation because I just feel utterly hopeless about my future and want to give up.
