Need advice

Hey so im here hoping i could get some help with my relationship problem. Me and my boyfriend are in a long-distance relationship for a year now,although we never met,things had been going great between us. But then two days ago,we had a fight and although i didnt really mean it,i told him that he gives me so much pain,i was just angry i didnt mean to say that. Now its been two days he has not texted me yet,im getting really worried,plus i miss him it hurts so bad that everytime i think of killing myself. I am not sure of why he is not responding to my text. It maybe possible that he felt bad cause of what i said and left so as not to give me more pain but then i told him stuffs more horrible and mean then that in the past but he never left,he said he wants to be with me at any cost. So i thought maybe theres another reason he's not texting cause once he didnt text for 5 days cause his mobile was stolen,so theres a possibility something like that might have happened or worse if something bad happened to him i wouldnt be able to live. I dont know what to do,where to go,who to talk to but then i thought of calling him to ask whats wrong and i dont know if i should call him right now or if i should wait for a week or two atleast just in case he must be busy and i might disturb him. I would be really greatful if i could get some advice on what to do,when to do and how to do.Im lost so please help anyone?
