am yisrael chai-
I can’t say it any better than “Climbing mountains” did.
Can you call your relatives and talk? We speak to our relatives in E”Y using Cucumber and it isn’t too expensive.
If that isn’t possible, can you go out with friends and just talk?
Since it’s erev Rosh Hashana, now’s a time that it isn’t unusual to call old friends you haven’t spoken to in a while – speaking to friends and relatives and catching up with them is a pretty good medicine for being lonely and alone with unhappy thoughts.
I hope things get better for you – have a k’siva va’chasima tova and a gut gebentched yor.
