Really bad health anxiety right now

Loose teeth are most commonly the result of gum disease but can arise merely due to loosening of the ligaments and tissues that hold teeth firmly in place. A loose tooth, however, is not a cause for such extreme concern. Your dentist can support the tooth using a dental splint that will bind the affected tooth to your surrounding teeth until the tissues securing the tooth re-affix it in place. Although understandable, there is no need for significant anxiety due to the fact that loose teeth constitutes a very common occurrence.

You don't mention your state of dental health or whether you've been diagnosed with gum disease but there are treatments to successfully restore the gum tissues to a health state.

Clicking of the teeth can result from a loose tooth as well but more often arises from misalignment of the teeth. This can arise due to the positional variations of the teeth themselves or otherwise result from disorders such as Temporal Mandibular Joint disorder that often results in misalignment and itself can produce a clicking sound.

Anxiety can most certainly be difficult to withstand at times and this is particular true for persons with health anxiety, with thoughts becoming a runaway train of sorts that focus upon the worst possible reasons for symptoms that may arise. You're going to be fine and your dental worries are unwarranted to the degree being expressed. As a side-note, always let the dental office know that if a cancellation by other patients arise then you'd like to move your appointment ahead and be prepared to adjust your schedule accordingly. Matters regarding your loose tooth with turn out fine.
