"You should get a Facebook."...

[deletethisone]

I know I'm making mountains out of molehills, but even the thought of some of these people even trying to connect with me again makes me really anxious. (That is actually the same argument my mother put up, hehe)

Tbh, I think you prolly need to get over this social anxiety. There are some instances where the anxiety should happen - if they're gonna do things like talk shit about you to your friends or do you harm, based upon previous evidence - then that's the sort of people it's understandable to be wary of, but if they're just moronic, annoying or similar, then maybe something like facebook can give you a limited exposure to get over that. If it's a failure, abandon the account. Mine remains abandoned, but for very different reasons (I know noone worthwhile on fb).

I know getting over social anxiety is very difficult... but imo... from my experiences... well worth doing if you can.

I guess, when you say it that way, if I do just try it, then it might help my anxieties, right? (I wish I could just be hypnotised to forget every single one of them so I wouldn't be afraid of any exchanges with them, tbh. So if they did find me again, I would be able to respond with "who? sorry, I don't believe we've met at all. :3" in all seriousness)

I used to think the exact same way about Facebook, but, as it seems you've found out, it's the only way to get/stay in touch with some people. (As I myself found out).
So I gave into peer pressure and got an account.
How's it impacted me? Not too much - I check it when I log on for 5 minutes. That's the extent of my dealings with it since I joined.
I remember I got a friend invite from one person from my old school that I, with no slight exaggeration, hated unconditionally. A guy who'd made my life hell for four years or so. At first, it did upset me; then I thought... why? I clicked ignore, and had a laugh about it... and I haven't heard from him since. Remember that you don't have to accept friend requests, or even put down any info whatsoever.
As for your friends, I guess it depends on how close you are? Is it really worth losing these friends over something like this? Facebook definitely has its downsides, but it does have its uses. It makes organising social gatherings/parties a hell of a lot easier. Its made keeping in touch with friends of mine living on the other side of the country easier as well. Cheaper than constantly texting or calling them (I'm poor, you see).
Eitherway, just remember that you don't have to be on it 24/7.

This is why I only accept friend requests from people I like and talk to regularly. You don't have to accept every friend request.

I find it makes it easier to arrange things, otherwise I just wouldn't be on Facebook.

Ah, Facebook...

...a lovely place to flaunt personal information for horrible people to use and abuse.
I shall have to politely decline.

With regards to your question, though... I say don't bother with a Facebook account. If I can't keep track of my friends in my head, I have too many "friends", I think.
So, I'm very supportive, in that regard.

As for the other thing... cutting off contact with someone over that might be drastic, however if they fail to respect your decision, then it's really not silly at all.

My two cents.
