Should I take 5htp for depression or tryptophan?

Neither. Frankly, there is little evidence that either chemical treats depression. Both substances may get absorbed from the intestine, but they don't change brain levels of serotonin. Even if they did, depression is much more complicated than 'low serotonin'. Many people get a placebo boost from taking such products, double blind studies don't show them to be effective.
Possible Help. 5-htp has been advocated as a helpful supplement for mood. It is possible that it would be helpful in mild depression, but it is not likely to give consistent benefit by itself for more severe depression.

May need more. It sounds like your symptoms are recent and reactive and that your doctor suggested an initial approach. Another supplement which helps with sleep is melatonin. However, I would check with your doctor about this. If your, symptoms persist, you may want to speak with a therapist about stress management. In addition, your doctor can prescribe an antidepressant if all of these options don't solve.
Therapy? Have you yet tried any form of psychotherapy? Typically, the optimal combination of things to treat emotional issues such as anxiety as you describe depression is medication (which, on your best day, is supposed to take the edge off symptoms) but the real gruntwork takes place in psychotherapist's consulting room.
