Hair color advice

I have an appointment booked tomorrow to see if I can fix my hair. But I wanted to check with some groups on Reddit to see if there’s something specific I should be asking for.
For the last few years, I’ve been dying my own hair and I was doing it too dark so of course layer upon layer it ended up being black and looks terrible on me.

In the past two weeks, I have done a color oops myself. Then a neighbor, who is a hairstylist, did two “bleach washes“. She used some sort of powdered bleach mixed with some high-end shampoo conditioner and some sort of mask concoction. After the second bleach wash she did put color on my hair. I told her I wanted it to be maybe a medium brown but it’s now red and I hate it. I have never had bleach in my hair in my entire life and I’m 51 years old so this is all new to me. I do not want to go back to a dark brown/black. My ideal color would be a light to medium brown, but I don’t think that’s possible at this point with the way my hair looks. So I’ve included two pictures of what it looks like now and a picture of what I maybe like it to look like in the future. Help! (I think red hair is beautiful. My sister has reddish hair. I just don’t like it on me. I am a very basic person and I just want Brown 😂)
