Feeling depressed and hopeless. Help.

Hello, I am a 27 yr old well settled girl. I recently got the job of my deeam. I always thought that once i get this job, i will be happy. But suddenly from past couple of weeks i have been feeling depressed and alone(because i have been single for more than a year ) . I was sure that i do not want to get married until i find someone that i love and really want to be with. But all of a sudden i am asking my parents to look for guys for me. I am not sure if this is a decision that I am taking because of all these emotional feelings that I have been feeling from past few weeks. I also find it very difficult to concentrate on things. Things that i used to love , dont interest me anymore. I am always distracted or confused. I am not sure if this is something i could get help with . So,posting this query to find out if i should be looking for psychiatric help .
