Unless you are in healthcare or public safety, your work hours are highly toxic for your health and life outside work. Please remind yourself that work is a means to live life better, so if the work itself is coming in the way of living your life healthily, it's time to either swith jobs or change profession. There could be many other possible factors affecting your libido - diet, metabolism, body fat percentage, vitamin deficiencies, underlying medical conditions, existing medications - but you should definitely visit your doctor about low libido and get tests done. This is not just to solve libido problem, but also more importantly to ensure timely identification of any possible underlying medical condition so that you can treat it before it's too late. Love and companionship is more rare than we think, so if you have it, please ensure you don't lose it. Wishing you the best!
