Thread: A little help please

I am able to translate some of this, however having trouble with the last few words (por si te pudo pasar algo). Can someone assist … thanks

‘Es bueno recibir noticias tuyas solo que ya me habia acostumbrado a tus llamadas y correos y cuando faltan me preocupo por si te pudo pasar algo’

This is what I have so far:

It's good to receive your news. It's only that I had already got accustomed to your calls and emails and when they are missing I worry …

It's not necesary to include any more word, however, it's not redundant if you put the word bad, because the context suggests that worries apply only for bad facts.
So......
...because something bad may have happened to you.

thanks sandra and canencia
