I don't think it's odd or silly - dissociation is sometimes necessary - but i don't understand why your therapist didn't address it after you asked for assistance with it

You could try asking her whether it is something that she thinks would be useful to address in therapy

I've had that experience also, where i tell a therapist something that is really uncomfortable or embarrassing and they just sort of shrug their shoulders - i had one that actually responded by chastising me in a way - telling me that my intense feelings of self-hatred were the easy way out - i still feel angry about it - it made me feel worse, 'cos it took courage to tell him that to begin with
