Hmm, I can empathize with you. But trust me, skipping a year or 2 is just running away from these things, when you end up skipping, you'd realise you are in a much terrible place than you were before.
Unless you start owning these things and think to do something about it, things may not change for the better. Take it from someone who has been there, done that. All that whining I did, it only pushed the existing people I had in my life.
What's the solution you ask? Nothing immediate or enjoyable. You'd have to work on yourself, if feeling home sickness, go visit home for a week and get back.
We don't make friends in a day, it takes time and consistently showing up. Things will improve when you put efforts into it.
Most relatives don't give a damn, but if you see, even you don't give a damn about them. When was the last time you reached out to them?
Lastly, you cannot expect life to provide you with positives. It's difficult to take in bad news, but stop thinking like it's end of the world, you are in so much better position where you have the power to change things in your life
