Gettting well and becoming whole in Christ begins with admitting you need help. If you are suicidal, ask for help- suicide is a permanent solution to a temporary problem. Things can improve for you. If you are addicted to alcohol or benzodiazepenes -sedatives- you must NOT stop suddenly, get medical help to withdraw safely. If none of these apply, it is still advisable to see your doctor and get some blood work done in order to discover any possible chemical issues. These things represent an important start, and acting on them will be a measure of just how serious you are about getting well mentally, physically, and above all, spiritually in Christ.
