I'm a big believer in tackling multiple levels of our existence at once. They interpenetrate and have synergistic  effects
First, do seek therapy!  This is a very important level and often overlooked. 
Much of what gets played out in the spiritual worlds starts here. 
Then after,  or during professional help, also do the work  at the Chthonic -Sublunar level per Helena Hex's advice.
At this level, if you are open to this type of work I would also recommend a 7 Day Uncrossing Bath. In this context, skull candles would work on the ancestral / karmic level. A white skull candle one would be appropriate. Some rose petals for self-love, may also be a very fine addition.
For more on the mental-to-emotional  connection, may I also recommend Mitch Horowitz's program here. Just do the work until you  are calm and have control over your imagination . Learning to be clam and centered, so you are no longer using your imagination to imagine the worst for yourself and others, or of the world, you are removing hooks in The Imaginal / The Spirit World that gets the attention of these diablos and muertos.

Avoid anger and other negative emotions also. This also 'attracts' them. ( Or creates them, as it thought of in a more modern frameworks, but whatever. Same deal. )
For Spiritual  / Above the Moon  level, there are many things to do. But too big a topic and I leave that to your personal spirituality and it's spirit allies.
