I'm not sure that the med will be effective but I do think it will need more than one week.
It's been my belief that self esteem comes from within and that your own actions are more important to healthy self esteem than the actions of others. Have you had any therapy to work on this issue? Poor self esteem can be remedied. Death can't be remedied. Why don't you give the med a bit more time and work on the self esteem.
