I'd say, AVOID IT! if you really really can. It can give you memory loss. It only wipes a bit of your memory. So no wonder you won't worry as much and have depression because you don't what there is to worry about. Shocking the brain isn't good! I'd say, seek professional help and take meds. Unless you are really like hanging by a thread on life.
Take care!
There is a safer and newer alternative for electroconvulsive therapy (ECT) it is called transcranial magnetic stimulation (TMS) and it is non-invasive.
''Transcranial magnetic stimulation (TMS) is a noninvasive method to cause depolarization in the neurons of the brain. TMS uses electromagnetic induction to induce weak electric currents using a rapidly changing magnetic field; this can cause activity in specific or general parts of the brain with minimal discomfort, allowing the functioning and interconnections of the brain to be studied. A variant of TMS, repetitive transcranial magnetic stimulation (rTMS) has been tested as a treatment tool for various neurological and psychiatric disorders including migraines, strokes, Parkinson's disease, dystonia, tinnitus, depression and auditory hallucinations.'' also can help for anxiety.
