Put yourself ‘out there’ more. Friends are very unlikely to fall into your lap. Don’t shy away from get togethers that you usually would and you’ll likely find people that you gel with. Work is a good place to make friends and you can branch out from there. Pre-established friend groups are also nice to get in on. Other than that, regular activities are good (gym, classes, volunteering etc) there are nice people everywhere (just avoid the dicks)
