Hi angela, Welcome to the depression board. Depression comes in many forms and presents itself in many different ways in each of us. I have had depression & PTSD for many years and within the last 5 yrs anxiety/panic disorder.
The best suggestion would be to speak to your doctor and let them know how your feeling. Perhaps a mild antidepressant would be in order to help...that is between you and your physician to decide. It does usually take anywhere from 4-8 weeks for most antidepressants to reach their therapeutic levels in your body even though you may start to feel some effects from them immediately.
Please do let us know how you get on...Take care
