I’m 19 and have been taking levothyroxine to treat my hypothyroidism since the age of 13. Lately I’ve experienced some deterioration in my mental state which I’ve been finding particularly disturbing. I’ve always had anxiety issues but in the last 3-4 months I’ve been either really distressed (often by simple things such as having to leave the house or social gatherings) or experienced low moods (these have been manifesting particularly when I’m alone once the anxiety has subsided). I am always tired and irritable, have little energy for things that used to excite or motivate me. My memory has also suffered and I’ve been finding it much harder to recall things I never had any trouble recalling or memorising things for my exams. Furthermore, I’ve been particularly disturbed by the fact that my thoughts have “slowed down”. By this I mean that I often can’t keep up with what is being said by someone I’m listening to (both in real life and on TV) as well as myself at times and I often have to replay it several times in my head before actually processing and understanding it. My mood swings have gotten to the point where I can be in a tolerant mood one minute and be on the verge of crying due to a minor inconvenience the next. I can’t help but be irritated at others and end up snapping at them, often without any reason whatsoever. I honestly wouldn’t have made a big deal about any of these issues if I hadn’t felt effectively stuck in this mood for the past several months and it only seems to get worse.
I was wondering if these symptoms were related to my hypothyroidism possibly deteriorating, particularly since a close relative of mine also has hypothyroidism and has been suffering from depression for years. Should I get my TSH levels tested (the last time I did it was last January) or are those issues unlikely to be related to my under active thyroid?
I’d be extremely grateful for any guidance as I had no idea whom to turn to about this.
