- avoid things that you know trigger negative thoughts
- try new activities to distract yourself from negative thoughts
- there are many essential oils that are thought to be mood lifters (
http://www.iheartoils.com/2013/02/22/happy-essential-oil-blend/ is just one example)
- exercise and a good diet are
huge contributing factors to mood
if none of that works, consider this:
depression and anxiety are often symptoms,
not a diagnosis
when was the last time you had a blood panel done, or had a consultation with a medical doctor?
my sister was recently diagnosed with hashimoto's disease, which is an autoimmune disease that has symptoms that are very similar to depression (and is often misdiagnosed as such)
if i were you, i would pay attention to your mood swings (look at when they occur, what sorts of things trigger them, any other symptoms that go along with them) and do a bit of research to see if there might be another explanation
