Suffered from severe depression and anxiety for 7 years.

I am suffering from relentless anxiety and depression with OCD symptoms as well. Feel suicidal every day. Have tried psychiatric drugs of every class, CBT, mindfulness meditation, Transcranial magnetic stimulation, 20 treatment of ECT and psychotherapy without relief. I am currently on 5 psychotropic drugs which aren't doing anything for my symptoms. Don't know where to turn for help anymore. The suicidal thoughts are very intense and frightening.
