When you have gone through a severe depression, even when the factors that have caused it (situational or biochemical) are in remission or have ended, you may still be having some moments of feeling down or anxious. This can manifest with having bad dreams, losing your confidence or being unable to focus. All of this is perfectly normal, but understand that you need to keep an eye on what’s going on, as you may be having symptoms of PTSD. Depending on how deep the emotional wound is, it will take you a little time to get used to not thinking that the world is crashing in on you in some way, shape, or form.
