To happiest,
Meds make getting and being open in therapy much easier. It sounds like you might need a new medication. Also, if you are on a SSRI, these can take around a month to start working; some clinicians will prescribe a benzodiazepine till that time (eg. Valium).
Also, if you have been on a med for a long time- let say Zoloft and now it’s not working, before you try a different med, make sure you have maxed out on the dosage of the Zoloft (or other med). Also, some mental illnesses require more than one med right from the git go.
