Sorry you are feeling a little down. Remember though that when we least expect things change. You may work in a laboratory and see many people who unfortunately have different ways of being and living life. Don't worry about that. You don't have to change; you don't have to move to another town. Be true to yourself. Somewhere behind all the equipment and the books and the oxygen ... there is someone who is thinking the same thoughts you are and who, perhaps, feels a little lonely too.
