I hear you, sometimes explaing your needs to an extrovert isn't so straight forward.

My Mum is extroverted, she will listen to me explain my needs, but won't actually HEAR me. It won't change how much she NEEDS and it doesn't really stop her coming to me for a reaction, for validation, for sympathy.

She doesn't just disturb my peaceful alone time either, she also always wants something from me. And that is the part that no matter how much alone time I get at home, its never enough to recover from her extra-needy extrovert behaviour.

She might do it a little less after speaking to her about it, but it is not 'less enough' for me. If I point this out she exclaims that she is leaving me alone, and say how long she left me that one time, and then make me feel like I'm being ungrateful for her efforts...

I also wonder if this has anything to do with her age and generation, not so good at understanding mental needs etc.

Noise cancelling headphones help... I'm considering a lock on my door...
