I'm 51 and have been with the same girlfriend for almost 19 years. She's great with me when she's home and things go wrong - really patient, stable, and calm. She helps me out if I tell her something is wrong. We've talked about what to do if she's not there, so I don't break stuff (not her stuff - I do have that much self control) or throw anything that could do any harm.
If you have a bag you can punch, that's good. If not, you can throw ice cubes at the sidewalk or driveway. I've even repeatedly smashed a whole bag of ice, picking it up and throwing it down again until the plastic bag tore too much to hold in the ice. It's also good to have a small number of people on a list to select from who have agreed you can call to let them know when you're in crisis. If I call my girlfriend, or someone else who has agreed to be on my short list, they'll know I need help calming down and will just listen to me and speak calmly with me until I'm doing well enough to manage on my own.
Being creative and letting someone you trust help you devise a set of alternatives can really help you handle these times better. I think it has strengthened my relationship to let my girlfriend actively participate in planning and dealing with tough times. It keeps her from worrying and feeling helpless to make things better. Also, I let her know when she's helping, because it reassures her, even if I still seem distressed. That's another thing that's made our relationship better. We work as a team, with each of us learning how to be better at planning, helping, and reaffirming what works so we can refine the process. It also makes it easier to say when something doesn't work, because we trust each other enough to be able to express concerns in a more calm way, as well as to feel more calm when hearing about concerns from the other person. This is really important to me, because I never want my girlfriend to feel upset by my actions, and she never wants me to feel lost and in pain.
