In the northern hemisphere, always dressing according to the season: bare arms in spring (however cold it is) and woolen jacket in winter (however hot it is).
Always remember the proverb: "This too shall pass." Your negative feelings won't last forever, there's a light at the end of every tunnel. It might not happen today or tomorrow, but you'll feel better eventually.
Blessed are those who do not fear solitude, who are not afraid of their own company, who are not always desperately looking for something to do, something to amuse themselves with, something to judge.
