Question

Please help me translate my birthday greetings to Japanese. Thank you!
Please help me translate my birthday message to Japanese (in polite form). Thank you so much!

I hope you receive a lot of love and success this year. 
I am so happy that you became a part of X. 
Please always stay healthy and full of happiness. 
I will always support you.

Answer

This is a kind of difficult request, because greeting messages are often cliche and literal translation would sound not natural. But anyway, let me try.

あなたにとって実り多い一年になりますように。
あなたがXの一員になれたことをとてもうれしく思っています。
どうぞお身体には気をつけて、ずっと幸せでいてください。
いつも応援しています。

Actually, the first sentence would fit better in the end, I think.
