Is it correct to sat "inasmuch as" here instead of as, since or because?
Patients are often unwilling to admit to stress problems inasmuch as they feel they are a form of social failure and it is important that symptoms are identified in order to avoid unnecessary suffering.

Please, correct all my mistakes. I should know English perfectly and if you show me my mistakes I will achieve my dream a little bit faster. A lot of thanks.
