I've had similar problems with focus and discipline. I've tried alleviating them by exercising (working out with the ROTC at 6 AM), eating well, making important commitments, doing Buddhist mindfulness exercises, listening to Eckhart Tolle, writing myself a contract that I signed in front of my friends/classmates, trying to create a startup with some good friends, and many other things that typically ended in (painful) failure. I had successes here and there, but the mental effort required to hang on until the end was often huge.
I have the tendency to make commitments and create relationships when I'm in one of my highs, and then proceed to fumble them when I inevitably reach a low. I dropped 2 semesters of college before I looked for professional help.
I started by seeing a therapist, not an MD. I found the sessions beneficial and they helped me get through a rough patch, but after two months things weren't really coming together. At my therapist's discretion, I saw a psychiatrist. I told him my situation in it's entirety. I didn't let myself think about trying to save face. I told him the grittiest details if I thought they were important for him to understand what I was going through.
I definitely had strong misgivings before making that step. For me the worst was "What if everyone goes through the same difficulties, and I'm just weak and cowardly?" However, my track record clearly showed I needed help. It was mostly a matter of allowing myself to be humble enough to accept it.
After only a week and a half of taking Seroquel, it's hard for me to say how it's going and where it's going to take me. Early though it is, I've noticed a change for the better. I like to think it's a temporary solution, like the way that you would put a tarp over a hole in your roof before you actually get it repaired.
Psychiatrists and therapists see people for things like this all the time. It's familiar territory for them. I could have saved myself a lot of heartache if I'd gotten professional help sooner.
Best of luck
