Could you plz share your past so we can decide how much is this forgettable and preventing you from moving ahead.  You should choose a therapist and tell your problem. Some time hiding or keeping the information only to oneself leads oneself to get  suffocated and unable to overcome his problem. Some time just talking therapy works and person gets ventilated himself.

Hello dear, See being stressed out for sometime or sad about something is not DEPRESSION..But yes you appear to be quite stressed out...try to find out major stressors and solve them..talk to someone close about it... Negativity about self, future, environment is an integral part of Depression...But it's manageable... Consult a Psychiatrist for detailed evaluation and Management of the case...It will help for sure..ok
