why won't my starter doesn't click when i turn the ignition anymore?

What is your question?

before my car broke down, i would turn on the ignition and my starter (i believe) wouldn't make that click. it was more like a zuhrhhh... it would sound really silent then it kind of choked and wahlah, it would start, but it sounded ugly, the choke i mean. it sounded like it scraped against something grainy and heavy and solid. THEN it would start up. and i kind of had to hold the key to the right for a minute.. almost like i was charging it. then i would turn i off once i thought it had enough power, and turn it on again and it would start. after that ugly chokey/scrape sound. now, the starter isn't even clicking or anything. i banged it with a yard scissor thing and tried the ignition again. it started clicking again, but my nissan still won't start. so i did that thing you can do with some standard cars. push started it. i pushed it until it had enough speed, then i jumped in the driver's seat, put it in first gear and ZROOM, ZROOM! i got it started. i left it running hoping it was just my battery and maybe it needed charging, but after i thought i charged it enough, i turned it off and checked to see if it would start again and nothing. no click again. can you help? any opinions on what it might be. anything would help. thanks.
