Need To Change Limiting Beliefs Fast

[SamEuphoria93]

I am overwhelmed by an existential crisis stemming from a complicated case of mental illness that is not adequately treated by medicines. There are multiple limiting beliefs getting in the way of my progress. How can I quickly and effectively overcome them?
Thanks in advance.

Seek professional help with your mental illness. The term "quickly and effectively" sounds like a catch phrase like "get rich quick". Real life's troubles take time to overcome. To cut to the chase for the "magic pill", the only thing holding you back is you. Now it may take days, weeks, months, or years to embrace and actualize that fact.
