you likely have autoimmune thyroid disease that may be going between hyper and hypo with times of medication induced hypothyroidism from the neomercazole (which is an anti-thyroid medication).   Now you are hyper again and given the years of back-forth, it may be time to consider definitive treatment with I-131 or surgery - would talk to your endocrinologist about this.
