There is a bug that is open right now which sounds like it might be one you were experiencing or possibly explains part of the issues.

Like the web browsing might have been from middle clicking, which causes a lengthy hang and resuming from suspend and powerdevil are a prime suspect for it.
The login wait might be an issue I vaguely recall about the splash screen and that disabling it removed the startup hang.
I’ve been exclusively using Manjaro KDE since September of 2021 and the linked issue I started getting a couple months ago and it’s gotten bad enough to make me want to start hopping again.
I recommend against searching for people to ‘make amends’ for a few reasons.
They might not remember it. Your attempt could trigger forgotten old memories, causing them stress you don’t intend.
They might not forgive you. Are you prepared to handle that? You make a gesture of good faith and they reject it, how to you react? That’s a rhetorical question, don’t actually answer it because no one knows exactly how they will react, it’s just something to consider and reflect on.
Trying to make amends would be you, trying to seek resolution to a conflict created by you, hoping for someone else to forgive you. Notice a pattern there? It would be you making things about you, which might be seen as a selfish humble brag or some may think it is part of a scam of some kind and trust you less.
It might turn out that the people you seek out have turned as bad as you once were, or perhaps they always were and you never noticed. Your efforts would be wasted on them.
That brings me to my suggestion. Move forward. Learn from your past mistakes to prepare for a better tomorrow. Do good things now, try to find ways to do it without getting any attention for it.
Don’t make your good deeds a badge to wear because then it loses its significance. An anonymous kind stranger is better than a politician donating to a fake charity, if that makes sense.
If you happen to run into someone you once bullied, apologize sincerely. If they seem down on their luck, ask if you can help in any way but don’t put pressure on them. You wouldn’t want them to feel ashamed for receiving help, right?
From now on, try to be a positive force. Do what you can to ensure the future has less people like you once were and more people like how you hope to be.
