Hello and Welcome--
What constitutes enough "trauma" can vary from person to person. Some people are more affected by life incidents than others....so "trauma" all by itself is not a useful measure of anything.
On the other hand, it is my understanding that Bi-polar disorder at its very nature is cyclical. They will be great for a while, and then bad for a while. They will swing from one thing to another. They may be hyper-sexual.
The fact that your daughter can be doing wonderfully for a while and then seemingly "relapse" may indicate Borderline (BPD)--not disprove it.
I am sorry that your family is struggling with this. I hope you can find some comfort here and know that you are not alone.
