Yes, that is certainly allowed. There is no competition as to who is in the worst situation. Your burden is your burden, and it is just as important as another person’s burden.
Experiencing trauma is overwhelming, but living alongside someone with trauma can also be difficult. You too will face the impact in daily life, may feel powerless or angry about the consequences, and it can be painful to watch someone you love suffer. The realization of what your loved one has been through can also be intense and confronting. All of this takes a lot from you and makes being a close relative sometimes a very heavy role.
Recognizing that it affects you and that you need support is therefore important. Taking care of yourself does not mean that you diminish the pain of your loved one. By paying attention to your own feelings and boundaries, you can better remain there for the other person.
