I've been running for 30 years, and 5 miles in 35 minutes was barely possible at the very peak of my training. There's no chance of pulling it off now, even though I'm in ultramarathon shape.

The point being, you run your pace. Congrats on starting and keeping up your running. It's a really good form of exercise -- inexpensive, readily available, and low-overhead. There will always be faster people, and there will always be slower people. You'll meet both at races (when races are a thing again), and mostly what you'll feel is camaraderie that you're all in it together regardless of your pace.
