Therapy.
I know some people can't afford it or don't think it's a viable option but you would be pleasantly surprised at what you can learn about yourself through having a professional hear you out. I've been seeing one because last year was a lot more traumatic than I could handle. It's been a blessing because my confidence in myself and the things that I can accomplish steadily increases daily.
I've been trying to do all of the things that make me happy, especially getting back into shape. Seriously, if you look good you feel good and have a contagious aura about yourself.
