MY tsh went down to 0.02..( indicating overactive) other test confirmed this..so .yours does seem to indicate hyperthyroidism.IWas on 125mcgms Levothyroxine for many many years for hypothyroidism so GP reduced L.thyroxine to 100mcmgs and blood test ater 2 months on reduced dose has confirmed that I've now gone back to " normal" rang for Thyroid Functions.
I wouldn't reduce it yourself without seeking advice from GP as I once did this and made myself quite ill.
Hello HiVi :
If hypothyroid and already on thyroid hormone replacement a low suppressed TSH does not mean you have become hyperthyroid and is not a reason to reduce your medication if you are feeling well on this dose of Levothyroxine.,
Your medication should not be reduced on a TSH reading but on where your Free T3 and Free T4 readings sit in the ranges as these 2 vital hormones should be balanced at around a 1/4 ratio with your T4 probably sitting in the top quadrant of its range.
very important to test vitamin D, folate, ferritin and B12 at least once year, but especially after any dose reduction
Low vitamin levels extremely common on levothyroxine and especially as we get older
Low vitamin levels tend to lower TSH
Most important results are ALWAYS Ft3 followed by Ft4
Always test thyroid early morning, ideally just before 9am and last dose levothyroxine 24 hours before test
Slightly elevated TSH
help ! Very elevated TSH 
Test interpretation - GP says I'm overmedicated on basis of low TSH
