Damaged voice box/ blood in secreations

I got sick 7 days ago, i had a fever, sore throat, horrible cough, but not really congested nor secretions... Ok so now everything is gone,  but i still have a cough and now i think i damaged my throat because blood comes out every time i cough hard and now i cant even say two words for the past 3 days.  I feel like i lost my voice and i am afraid that i wont be able to talk normal again... i dont have insurance so i asked the this question online... My question is how do i heal the "broken cappilaries from my throat that makes it bleed, and second is there a way to get my voice back??? I could say one word then right after it comes out as a wisper.
