As you have high antibodies it would appear you have an Autoimmune Thyroid Disease called hashimotos. This is the commonest form of a thyroid dysfunction.
When you post your results it is helpful if the ranges could also be included. This is due to labs using different machines that have different ranges.
I shall give you a link and it will explain better.
The antibodies wax and wane until you become permanently hypothyroid.
Usually, the treatment with high antibodies but now also that your TSH is far too high, you do need a prescription for levothyroxine.
If you were on levothyroxine previously, the doctor probably didn't increase your dose sufficiently until TSH was 1 or below. Some doctors imagine that once TSH is 'somewhere in the range' that their job is done. Not so. We have to read and learn and many have found going gluten free very helpful in hashis.
When you get blood tests always get the very earliest appointment and fast. If you take thyroid hormones allow 24 hours between last dose and test. Levo should be taken first thing with one full glass of water and don't eat for approx 1 hour. Food/coffee interfere with the uptake.
Always get a print-out with the ranges for your own records and post if you have a query.
