I understand your situation. You seem to be suffering from depressive symptoms including low energy and absent mindedness. Information regarding your sleep, hunger and
thyroid levels also would be more helpful to decide the severity of your condition. However it is easily manageable with appropriate treatment. Some counselling sessions along with medical help also might be useful for you. You should learn to be assertive with your girlfriend regarding your personal space. I would also be more than happy to help you with that if you are looking for online assistance. Discussions will be held confidential. You can directly consult with me through Practo as needed. Online chat consultation is available.
