This isn't exactly on topic but I believe it to be an important matter so here goes:
I can tell you first-hand how it feels to be on both ends of the social scale. I used to be a very isolated person. If a person gave me a single significant reason not to like them, I didn't want to have anything to do with them. I didn't tolerate imperfections. At all. As a result, I ended up being a grumpy loner whom nobody liked and who didn't like anybody.
This, unsurprisingly, led to depression paired with anxiety around people. As it is common for depressed people, I evaluated myself very harshly. On one hand it wasn't healthy because it made me resent myself, on the other, though, it actually was good for me, because I came to realize that there are things about me that I don't like but that are true. I've been working on those ever since. I'm ashamed that although there is some progress, it isn't great.
A few months ago I went to a new psychiatrist in a whole different clinic in hopes that they would put a little more effort in my case than the old place I used to frequent. They did. The new psychiatrist asked me a bunch of questions, had me tell her a bunch of stuff and in the end she assigned me to a therapist and prescribed some different pills. She was surprised that my previous clinic didn't do that.
Shortly after something broke inside me. I have no idea if it's the result of the new pills or whether I just got scared by a psychiatrist actually immediately assigning me to a therapist rather than just giving me some happy pills, but I changed. I rekindled some of the old acquaintances. I started talking to and meeting people I broke contact with years ago because I couldn't tolerate them.
As a result I now actually go out. I go to parties every now and then. I meet new people. Most of them still bring my blood to a boil for various reasons but the point is: I've turned my life around... well, at least a bit.
And I've got to tell you; it feels better. One thing that scares me is that I've had periods during which I felt fine, almost happy, before. I always eventually relapsed into misery. Previously, though, it happened for no actual reason. It just did. This time I've actually made changes. My psychiatrist says that it's most likely a temporary situation anyway. The depression I've had for years isn't likely to go away forever just because I changed some things.
Still, the situation, such as it is right now, feels good. It feels better than loneliness. A few months ago I wouldn't have said this.
BUUUT back to the topic: I would personally recommend getting a proper, old fashioned mouse. They used to make that stuff a whole lot better than they do nowadays. My mouse is A4tech X-710. I recommend it to anyone. The wheel still works like new. It has an adjustable DPI tapping out at 1000 (and let's be honest, you don't really need more than that), and if feels good in my hand despite the simple, seemingly office-oriented shape. I also recommend any Microsoft mice. They might be the company that made Windows Vista but they sure do make damn good peripherals. Be prepared to pay a pretty penny for those, though.
