I have been feeling very low in mood, not sleeping properly, haven,t been going out lately since splitting with my girlfriend a year ago and I have no friends as I lost touch having traveled a lot with my job over the years, i,m a 52 year old male, spent christmas and new year celebrations on my own which hasn,t helped as I could not be bothered with family members.
Hi, Welcome to Chat Doctor forum.  As you describe it appears that you are running away from the situations, and developing depression. You should come out of this situation.  I advise you to consult a psychologist for diagnosis and treatment.  Practice yoga, meditation, reading books, and hearing music as a diversion procedure.  Take more of green leafy vegetables, pulses, sprouts, and protein rich foods for good health.  Wishing for a quick and complete recovery. Thank you.
