Looking for advice

Very extensive family history of diabetes so I’ve always been pretty aware of it in myself. I do my best to stay active and eat healthy, which is probably why I noticed this in the first place. I noticed a pattern with periodically feeling really weak, shaky, dizzy, angry, and nauseous throughout the day. I would just have a snack and normally be fine. My partner suggested taking my blood sugar before snacking and I started noticing some really low numbers. Mostly I’d find 50-60’s but there have been some bad instances of 40’s where I felt like death then proceeded to drink half a carton of orange juice. The worst instances have caused me to blackout. I was terrified that I started checking at other times throughout the day and keeping a food log. I never really got high numbers like I’d expect to see with diabetes. But what I did notice was between 2-2.5 hours after eating I’d be in the 60’s. If I waited longer to eat then I was entering some danger zones. Im not on any medications, have a normally functioning thyroid, and I’d like to say I’m not too concerned it’s cancer. That just leaves me with hypoglycemia as an answer for now.

I’m not a doctor and I will try my best to see one soon. I’m in between jobs rn with no insurance so it really does have to wait. But I’m hoping for some advice from anyone having gone through something similar on how to handle this in the mean time. Really, any advice would be beyond helpful.
