TSH >2.0 indicates thyroid is beginning to fail but I can't tell whether FT4 is within range as you haven't included ranges. NHS won't usually diagnose hypothyroidism until TSH is over range or FT4 is below range.
Thyroid peroxidase antibodies are positive for autoimmune thyroid disease (Hashimoto's). There is no cure for Hashimoto's which causes 90% of hypothyroidism. Levothyroxine treatment is for the low thyroid levels it causes. Many people have found that 100% gluten-free diet is helpful in reducing Hashi flares, symptoms and eventually antibodies.
Hashimoto's often causes low vitamins. Get vitamin D, folate, B12 and ferritin checked. Make a new post on here when you get the results including ranges
Meanwhile you may find changing to a gluten free diet helps reduce symptoms
