grounding is going to be key. It sounds simple but it is easier said than done. But if you can remain grounded you'll still feel everything but you'll be able to chose how you respond.
I am a big fan of metals and crystals but they are not for everyone. If you smoke cigarettes I recommend ceasing as it can amplify what you feel making it harder to control.
If you're into meditation, yoga, or any kind of energy work those can help.
I also attend therapy. I do not share my gift with my doctor but we work a lot on being in the moment and mood regulation. Which is a great help.
Also diet can be very important. These are things I have worked on for years that can have really changed my life.
Hope this helps.
