I agree with Joe, it's always a good idea to deal with your basics first(diet, supplements, sleep, exercise, creative activities, etc.). It could very well be that you don't have a lot of energy reserves to begin with, and if that's the case then figure out why and work on that.
If you really feel there something else going on then the other thing to consider is if you are the one giving your energy to him, and not him draining you. I have read that many/most caregivers do not establish healthy boundaries with their clients and end up either taking on other people's suffering or giving their energy away. Gaby's advice is perfect because with that intention you are choosing not to identify with him. You are intending that you as an individual will help him as a separate individual, instead of you becoming him which leads to you giving away your energy. IF this is happening then before you engage with your clients develop a habit of intending what the interpersonal dynamic will be like and don't pity, empathize, carry his emotional load, or anything like that. It's his job to manage his psychological wellbeing and your job to help maintain his external environment.
You can also do what's called a neutral separation when you're done, in case you forget yourself, by naming 5 simple things that differentiates you both(i.e. he has black hair, I have brown. He is male, I am female. he has a dog, I have a cat, etc.). The intent is to fill your EM field with your energy if you've given it away and give back anything you've taken on that doesn't belong in your field. Keep it simple, down to earth, and go about your rosy way.
Hope this helps.
