YES! you can get better. i used to only get the dp during a panic attack but a year and a half ago or so it came on full force and didn't leave for two weeks. rather, it was really strong for two weeks, a constant. then, for the next year or so it was always kind of there. sometimes it would come on strong, other times it was lingering. but i'm so much better now. i feel good. i'm not scared anymore. life feels normal. at times, when i'm trying to avoid feelings or decisions or "checking in" on myself, i will feel it a little more strongly. but, really, i tell myself that i've had it before, it didn't kill me, and if i get up and do something it usually goes away. it really really can be overcome.
coming here helped a lot. there are some threads on DP/DR that changed a lot for me. check out these three threads. they're kind of long but well worth the read. i printed them out and carry them with me. i haven't had to look at them that much but they're good reminders. hope this helps.
