About 15 years ago I had a long-term relationship break-up, saw my own small business collapse and, worst of all, suffered the death of my father - all of these happened within six months.
The answer I had then, was to throw myself into more and more work to try to dull the pain. Fortunately, a good friend suggested that I go away on holiday before I killed myself through over-work; she whisked me away for a break and It was amazing what a week away did for me: I calmed down, cut back on my work and within a couple of months met someone and started a new relationship.
I hope your friends are looking out for you but the advice of taking a break and trying something different sounds a good one to me.
