Your English is perfect. There is no indication of low intelligence from the way you described your issues. B and C grade are pretty average and indicates you can learn with hard work. I think what you might be experiencing is anxiety and that is causing you to think you don't have skills or intelligence. I am not from US so I don't know what kind of help might be available for you there, but I would suggest you to look for a job with something you like to do even though the pay might not be great and then eventually your interest will take you further in your career.

That explains why MullvadVPN keeps disconnecting on Android.
GrapheneOS is the easy to install OS among any mobile platform. Everything is through a web UI, so you are very unlikely to brick your phone. You don't need to type a single command. Also even if you brick a Pixel phone, it's very easy to install stock Android build through Google with a similar installation process.
It's really impressive what GrapheneOS is doing. With a such a small team, they are able to push so many features that just works. I think average consumer does not realize the value of this project. With constant surveillance of Apple and Google, GrapheneOS is the only high quality alternative we have. Whoever reads this, please use GrapheneOS and donate if possible.
