I NEED HELP! Head lice

I posted about head lice last night but didn’t get much feedback. I’m hoping I get some now. I can’t get the comb through my own hair. I keep ripping my hair out. I’m getting so frustrated and don’t know what to do. I can’t even brush it with the brush I use everyday. I’ve gotten one bug out and I’ve been doing this a whole week or a little bit longer. I just did the mayonnaise treatment but idk if I did it right? Am I supposed to use lice shampoo after or regular shampoo and conditioner? I still haven’t found anything in my daughter’s hair but she is still itching a little. I literally have no money to get a haircut or anymore treatment and I just used up all the Mayo I had. I still feel bugs but my scalp is also so irritated. The shampoo was burning a little bit. I need all the advice I can get right now because I’m losing it /:

I just don’t know what I’m doing wrong. I have plans for Christmas eve so I’m hoping i can get rid of it before then.
