All problem you mentioned are core symptoms of depression are sadness, low mood, lethargy, disturbed sleep, low self-esteem, irritability, suicidal thoughts, decreased concentration. I think you should consult a psychiatrist, personally. Usually, there is insomnia in depression, but some time hypersomnia also possible in atypical depression. You do not need different medicine for all of your problem they will be solved just by antidepressant medication. No need to get panic and getting rid of depression is not so severe nowadays. Various new antidepressants and psychotherapies are present. If any stressors present try to remove it or decrease impact in life, improve your coping. Moderate exercise, yoga, meditation may help you. (rule out the medical cause by an investigation like CBC, TSH calcium B12, D3 level).
