Those levels are "normal" so far as it goes, that is... They are within the so-called "normal" range, but they are probably not "normal" for you
. The TSH is high for someone in treatment; about 1 or even less would probably be optimal, because that's what 85-90% of the population without any thyroid problems has. Yours at 2.4 is nearly hypo by definition, which is anything above 3.
Your FT3 is below the middle of its range, which says it probably isn't high enough to meet your needs. I'm not sure why your FT4 wasn't tested as well; if it too is below the median range, that means you're definitely undertreated. A smart, sympathetic MD would increase your dose based on those levels. That's really what should happen next; I hope you have a caring doctor who will grant your request for a modest med increase, because I do think it's warranted.
I'd be pleased if you let me know what happens.
