Is this silly? Rash from years ago

Hi friends,
I hope this isn't a silly question... First, brief background, I have been dealing with numerous symptoms for about 20 years now, no doctor can explain. Weight loss/inability to gain, hair loss, fatigue, Neuro symptoms started 4 years ago, etc.... When I tell you I've been tested for everything under the sun, it's not an exaggeration. I feel fortunate in that everything is "normal" but I know my body and have been tortured for over 2 decades with these symptoms. Anyway, here's my question... If your immune system is robust and you are infected with lyme, can your body fight it on its own? As a child I remember showing my mother a bullseye rash on the bottom of my foot. She dismissed it as ringworm and of course I didn't think twice. I don't know why I remember this but I do. I'm wondering if it was really a Lyme rash and could I be harboring Lyme for decades. I thought I remember hearing that not everyone bitten by a deer tick will get Lyme because the immune system will eradicate it. Anyone have any thought on this? Thanks for reading. Be well.

Lyme and its co-infections can be opportunistic infections or "stealth microbes," meaning they wait until your system is weakened in some way (stress, another illness, trauma, etc.) before gaining a foothold and taking over. Here's an article from rawlsmd.com that explains some of what I am referring to: https://rawlsmd.com/health-articles/chronic-immune-dysfunction-lyme-disease
It's absolutely possible that you were infected long ago. Absolutely.

Never worry about a question seeming silly. I'm glad you reached out!

Thank you so much for replying, very helpful. It sounds like once you are bitten, the bacteria just hangs out until it finds the time to strike. This would make sense as my symptoms got really bad with my dad's illness/passing. I haven't been able to recover since. Now I need to find a way to heal... Thank you for being so kind, I appreciate the help. Be well.
