Ok well what I meant was that these are symptoms and there must be underlying insecurities causign these symptoms, related to the life you have led.1. inappropriately high pitch, strained voice,
2. tremor or shaky voice.
3. Lack of ability of self-expression.
4. weak gentle voice.
5. weak and gentle movements or behaviors.
This is hard to know.
But I get the feeling this isn't the kind of advice you're looking for so I'll go with - yes, take up going to the gym regularly. I did that when I was 18 and it changed my life forever.
