My Blood-hypo what?

This post may get a little personal and a little serious at first, but I promise you will chuckle at the end.
Since the birth of my daughter (a little over a year ago), I felt like something inside was a little off center. Lots of people attribute it to the post birth blues...and then when it didn't leave....post partum disorder. It wasn't "depression" in a typical sense. It was kind of erratic and hysterical feeling.
A lot of people believe in talking to someone to talk through their problems. I took that advice at first. Utah has a new mental health building that looks fancy and authentic. When I talked to them, they wanted me to come in everyday for a four our group meeting. (Hello, I have a baby and I work full time...thanks for nothing).  I talked to my OBGYN, clergy, my mom and of course my husband.
Blah blah blah and it didn't feel better. A few months of that I took it inside and tried to handle it myself. That worked for a while, but it built up and slowly the release happened once every few weeks, then every week and than it hit a scary point for me when it started happening for days in a row.
Dave, my husband, has been a fantastic listener. Hearing my complaints and crying like a champ but even he has his limits. The company he works for has this "mental health campaign" or something for their employees. I took him up on it and met with a counselor, who is fantastic. I have a difficult work schedule and it is hard to find a babysitter for additional hours outside of work, so who knows how often I'll be able to see him.
His first suggestion was to get all my blood levels checked. As if my countless blood draws (to check my cumidin levels) during and post pregnancy weren't enough. Oh needles, it's a good thing I'm not afraid.
So I go and check, fill out more forms on depression and anxiety. I could probably recite them in my sleep I've read them so many times.
Results came back today and all my hormones look good but something awkward showed up: hypothyroidism.  I know thyroid problems run in the family but  I have no idea about what it means. Underactive thyroid, which means missing stuff.
So I'm reading symptoms and stuff: weight gain (not really), dry face (yup), aching joints and muscles (YES), feeling sluggish & tired (sure), depression (yup).  These things have increased over the past year to crazy levels.
Then I read the "people at risk". Women over 50 and/or a genetic predisposition. I'm only 25. What if I didn't find this stuff out now? Would I be dead by 50? Probably not, but I thought the blog universe would enjoy knowing that my body apparently thinks I'm a 50 year old women. Tell that to my monthly visitor.
