Your bf may feel like you won't need him as much if you get help somewhere else. I don't know your whole situation but it may help to let him know that you are seriously concerned about your own well-being and that you want to be in a good place so that your relationship can be better. Ultimately meds may not be for you, but that is a call only you and your doctors can make. If he is truly supportive, he will want you to be healthy and happy.
