I have to agree with Alex. It's almost a caricature sound, largely because you're forcing the voice up to 240hz+ which is much higher than it needs to be or would ever sit naturally given your current physiology. Frankly it doesn't even matter what your pitch is if the resonance is correct. Seeing a SLP is definitely a good idea!
Meantime, go listen to some Kate Mulgrew, Whoopi Goldberg, or other low-pitch female voice actresses and start by trying to imitate them. Don't try to go higher, at least initially. Focus on larynx position and prosody. I swear, people on this forum would be amazed if they realized how low the pitch of many popular / commercial female voice actresses really is.
How low have I heard them go?
Mulgrew - 100hz, seldom over 200hz
Many - 110-125hz
So common it's not even remarkable - 130-145hz
