Please do not be so hard on yourself. At the end of the day, you have to move forward. The pandemic had an impact on so many students in so many ways, and colleges are well-versed in parsing through what that means at this point. Your upward trend, rigor, and solid ECs will help so much. If you score well on the SAT, that will only help to confirm that your freshman year was an anomaly. And, as many have pointed out, different colleges have different ways of recalculating gpa. This could work in your favor.
What I would do for sure when it’s time to apply is to save explaining why your freshman year was hard for the Covid question on the common app. Don’t make your essay about it as well. Also make sure to go to AO visits at your hs and college fairs in order to make a personal connection with AOs. Demonstrate interest wherever possible, and have a solid list of schools that includes genuine likely and safety possibilities in addition to reaches.
You can’t change the past, but you can present yourself in the best possible light and try to give yourself some grace at the same time! Deep breaths. It’s going to be ok!
