Just because you are not strong in feeling functions doesn't mean you don't have feeling, I think it just means that you might be a little inept at identifying and dealing with them. To someone that it doesn't come naturaly to it takes more practice and focus (like me with T). Developing F doesn't mean being controled by your emotions and having a better understanding of why you might be feeling certain ways enabled you to better respond to your reactions.
As a T it might be beneficial to, when away from situations, go through a logical process of cause, effect (feeling), response. Also, some feelings are not appropriate to the cause, which can lead to more analysis of what deeper feelings might have caused you to respond to a situation in an inpropriate way. You can apply this process to see what feelings motivate other peoples actions. Then combine both approaches to determine the appropriate response.
