Man.. It's a LITTLE hard to read what your writing, but I hear what you're trying to say. It could be battery OR alternator. If you can get your car to an Autozone, or ANY shop/parts store that can test both of them for free, DO IT. It does sound, however, that the battery is done. Think back to the last time you had it changed. Also, take into account that if you get a NEW battery, but the alternator is the problem, it's going to weaken the battery, even after you get it recharged from the drianage it's going to undercome. An alternator is a more expensive issure therefore, have them both tested, because going the cheap route could end up costing you more $ in the end.
Hope it helps.
