The reason I asked about the Sugar is because what you're experiencing sounds to be beyond normal social response to the love bug. I believe your body is over-reacting to the love stimulus and you may suffer a lull in health when the stimulus subsides. Even if these events in your life continue strongly, your body may shut down eventually for a short period while you physically recuperate.
If I'm right, I can tell you things to fortify yourself with results in rather quick period of time. If I'm wrong, I apologize in advance for my assumptions.
