I've had migraines since I was 16 and this year I've also suffered from depression. I've always had bad mood swings and fairly irregular periods (not massively out of sync, but unpredictable) which are very heavy for the first few days. I often get tired during the day, even when I've had enough sleep, and I'm a bit of an insomniac at night. I'm not hugely sensitive to the cold but everyone comments on how much colder my skin feels than theirs, and winters are always bad for me because after a brief walk my hands turn into ice blocks. I feel like I've gained a little bit of weight lately and noticed it before I even started thinking about underactive thyroid, although I'm not sure if it's just psychological. I did start puberty reasonably early - not abnormally so, but I needed to wear a bra by the time I was 10 and all my adult teeth had come through by the time I was 8 or 9. Recently I've been getting a few aches and pains in my arms, although it's too early to tell whether they're frequent or just a coincidence. I also have a family member with an underactive thyroid.
All of these symptoms match up with UT and I'm going to try and get a blood test, but is it possible that I'm misdiagnosing myself by making the symptoms fit, as someone said earlier? My hair isn't falling out, the skin on my face is dry but not noticeably so, and I've been feeling much less depressed lately. I guess what I'm saying is, is it possible to have only some of the symptoms? It sounds weird but I'm really hoping I do have a UT because it would explain so much - I've struggled to find a unifying cause for all of my health problems and mood problems, and knowing that it was something which is treatable would be really reassuring.
