How Do I Get Over Home Sickness?

I've made no friends and feel very isolated. I don't want to give up on uni, but it's getting to the point where my mental health is suffering. You actually do have to think about what you're doing and what is your why. If you're not finding your groove down there if you're not working, that is not failure. Do a list of pros and cons - always do a little pros and cons list. And don't do it because you think you have to.
