I think, in all honesty, the first place that someone in emotional distress should turn is their loved ones, and then to use professionals.

Keep active - do something physical each day. Could be as simple as taking the dog out for a walk (if you've got a dog!), but could be going for a swim, or going to the gym every day.

When you notice an unhelpful emotion or a shift in mood, or when you notice that you're doing something you know can cause problems (being snappy, for example, or drinking too much), that could act as a cue to examine your own thoughts - "what am I thinking?".

Maintain your relationships - for all kinds of reasons, friends are vital. Good friends, supportive friends, friends who won't judge you or try to take advantage of you.
