New computer

So, never done this before, but I’m hoping I can get some help. Long story short, last year I wound up losing everything that mattered to me, have to stay with family until I save to move, and hurt my arm. I am currently working insane hours, most weekends included, outside in the cold. It’s a job I love, so that’s the good thing. The bad thing is that when I get home all I want to do is relax and play some video games or something with friends, and I am no longer able to really use a controller for my PlayStation. More than 10 minutes and my hand loses all feeling and pain shoots up my arm. I have found that a mouse doesn’t case the issue, so I am trying to get a good computer that will last a while, but can’t do it on my own because I need my own place as well.

If anyone is willing to help, I’d be greatly appreciative. Thank you in advance and hope you all that read this have a wonderful day
