What Causes Irregular Periods With Tiredness And Weight Gain?

Hello! I'm a 36 old female.Lately I've been suffering from horrible painful tiredness,weight gain without any diet changes,back pains and many more.The blood tests showed high TSH levels with normal thyroxine and high estradiol and prolactin levels.My periods are a total mess.Also I've been noticing for some time now that every time I eat something sweet I'm having an inflammation in my eyes that passes in a few hours.What can it be? Can it be some form of a diabetes? Or is it all coming from my thyroid? Please please help! This thing is killing me..Thank you so much for your time! Julie
