I will assume "bac" is a name or something short for cousin or something else.
I'll try to translate it quickly.
"I'm good BAC, we're at work, it's cold, thank god winter passed i can't wait to come over there and get warm. I see you put up some photos, somehow you got even more beautiful, it seems like the warm weather does you good. Enjoy the heat, I envy you. Bye bye.
Hi, BAC, i'm interested if there is any reason why you haven't called me. Call me or send me a message, i'll give you a call, I just want to hear from you. Bye.
BAC, whats going on? Are you OK? Why are you not calling?
BAC, I'm really nervous, I haven't slept all night, call me somehow so I know whats going on?"
