I have a thyroid from past 1 year... I become fat day by day... sometimes I feel tired also, my hair is also falling daily... for all these I need solutions...

What medication do you take? Are you being seen by a good endocrinologist?
It's difficult to lose weight when on thyroid medication so a healthy diet is most important. There's just no room for junk food or empty calories like most breads and pastries and desserts and chips.

I think you need to go back to your Doctor, tell him of all these problems that you are having.

It may be that he can change your medication to something that will suit you better,which might also stop you from gaining any more weight.

You could also ask him for a diet sheet or maybe he can refer you to a dietician who will help with the weight problem.

You say you are very tired and that your hair is falling out,tell your Doctor this,it maybe that you are also suffering a deficiency somewhere.He probably will take a blood sample to confirm if this is the case.
