Я умираю от тоски по тебе!

My longing for you is killing me!

Мы оглядываемся на прошлое если не с чувством привязанности, то в любом случае с каким-то подобием тоски.

We look back on days gone by, if not always with affections, at any rate with a kind of wistfulness.

Он вернулся домой не из-за тоски по родине, а из-за того, что у него кончились деньги.
