I am begging you for your help

Hi. I really need your help. I have a 1996 geo prizm 1.6L. The other day got stuck, was able to get a jump and made it home. When trying to start it up nothing, no click, no nothing. I had the alternator, battery, and starter looked at. Everything is fine. Also checked out all the fuses. I heard it could be the fusible link wire or maybe a bad connection. Please tell me if any of this sounds right. I am in a really bad spot financially, and could really use some expert advice.

I swear if u help me out I would glady come back and donate. I am saving whatever money I do have for repairs. But if u can save me the mechanics fee. I would rather give it to someone who out of pure kindness decided to try and help me.
Thank you.
