It feels like it will never end

I need to finish my Masters degree. It is not something I have ever wanted, ever, but it is something required in my state. I have been enrolled in a summers-only program for the past 5 years. It is a 3 year program. To be fair, I have had 2 kids within that time. One summer I was hugely pregnant and my brain felt like it was misfiring at every turn. Last summer was out because I had a newborn. I have hated every second of the program, even though it is a high-quality school. It has cost me an arm and a leg. My undergrad has been completely paid off for about 3 years now, but I owe about $20k on this, not to mention the semester I paid cash for.

Here is what remains. Mind you, my degree is completely paid off, I just have to finish up these loose ends:

• Write my Philosophy of Music Education
• I took an incomplete in the class where this was required. I have written and re-written it but this has proven to be very difficult. They are big on "music for music's sake" there, but what is someone who is in constant fear of losing their job to do? Am I just supposed to write line upon line about how music is absolutely the most important subject of all time and people who don't think so are just morons?
• Pass a comprehensive exam on early music history
• I just really need to buckle down and study for this. My reading/learning comprehension skills have been very lacking in the past few years. I was recently diagnosed with CAPD, a learning disorder. It explains SO much about my struggles in HS and undergrad. I wish I had known 10 years ago. This test is on the Renaissance through the Baroque.
• Pass a sight singing exam
• Sight singing was my #1 weakness in undergrad. I can do it, and thankfully I have 3 tries. Mercifully they allow singing on "la" instead of requiring numbers or solfege.
• Polish up my portfolio
• Unlike most colleges, I have no thesis requirement. I have to have all of my graduate work bound together and explained in a large book that will be judged by my committee. This part is nearly complete and actually I like how it is turning out.  
• Write and present on a topic relevent to my field.
• This is a 20-30 minute presentation. I have no earthly clue what I want to write about, I have changed my subject about 15 times. Then the committee gets to grill me. I have to study everything I can about psychology of music, learning theories, current big-guns in the field, etc. Even thinking about this gives me hives and makes me kind of teary-eyed.

I just can't put this off anymore. I need it to keep my certification. My difficulty here is that I don't believe in a Masters requirement. I don't feel it is necessary. If we had moved to this state a year earlier, I wouldn't be in this mess. I want so badly to believe in it, but I just don't. Maybe it is because I am so scared. Whatever it is, I have to do it. My advisor isn't the most cooperative of people but he isn't a bad guy, so I know he will try and guide me to where I need to be (if I can get ahold of him!).
