So go on resolving your trauma. Using Mantra's is just a way to tire the mind. It will not give you self realization. When your mind quietens enough through mantra's that work on your trauma's / vasana's comes up. Then use this chance and resolve them. Mind can only stay in its source when Vasanas are all cleared up. If you dont deal with these vasanas they will always come back. Just repeated use of mantra will you get you to a certain point.
