Yeah..it can be a challenge to motive oneself to keep going.
Things that help me:
1. Make a list of things you're happy for-i.e., In my case, I'm American, I speak English, I can see, hear, move, pay my bills, etc.
2. Take an early morning walk to set your thyroid mood thermostat
3. Switch to fresh, mostly raw organic produce, eat raw nuts, fish and organic eggs, while avoiding processed food and soda.
4. take herbs that balance hormones, raise your mood, like St. John's Wort, 5-htp, magnesium, iodine, Vit B complex, powdered root beer (MX sarsaparilla), etc.
5. listen to music you love, watch comedy shows/movies
6. do what gives you the most pleasure..play an instrument, draw a picture, message a friend to hang out, go to the movies, ride a bike, go swimming, play tennis, play pool, play ping pong, throw a football, play basketball, etc.
7. cuddle a pet, or throw a ball for a dog to chase.
8. read a good book
9. drink a lot of water
10. If you're old enough, sip a microbrewery beer in a quiet bar.
