Don't go. I saw that you said you've been depressive since you were 13. You've managed so far without being institutionalized. How will being in the hospital change things? Most likely they'll force you to take meds. You can do that without being institutionalized. Also once you go in, you are locked in. You go in voluntarily, but leaving voluntarily is another matter.
I don't see any reason for you to go in except to force drugs in you. Before going in, you should at least try some meds. Ask for the smallest possible dose of the safest drug with the least side effects. Monitor yourself closely and have your SO monitor you also. If it helps, with no serious side effects, then it may do wonders. But until you try that first, going into a mental institution is just too radical.
You've been dealing with this since you were 13. You know your condition. What has suddenly changed after all these years? Has it suddenly gotten worse?0
