You need to find a way to development mindfulness. There are many apps but when you are talking about being able to manage your feelings, think of this way; those monks who sat down and burned themselves alive as a protest...that's what mindfulness can do.

Sam Harris has an app called Waking Up that, in my opinion, is one of the best courses on breaking down a rather complex skillset. Good luck.

The mindfulness well help you recognize when you are starting to allow an emotion to build, so if you can catch the snowball when it's tiny, it won't become an avalanche and wreck your life.

EDIT - I couldn't be more emphatic about this - other than getting 8 hours of quality sleep, prescribed medication or therapy, this is the next best thing.
