Married 12 years, love him like a friend

I really need some advice and some help because I feel so alone and like the worst person in the world.

For the past 12 years I have been married to the most wonderful man known to all mankind. He is honest, loyal, supportive, kind and loving. Everything I or anyone could ever wish for. He has loved me through thick and thin (Literally weight wise) and I hate myself so much for saying this but I am feeling like I don’t love him anymore.

I was initially diagnosed as having Major Depression with Suicidal Ideations and now they’ve changed the diagnosis to Bi Polar and through all of it I loved my husband. There were times where I didn’t feel affectionate but always I knew I loved him. It wasn’t until they began to reduce my effexor from 412.5mg per day by 37.5 per week so that I can just be on Bi Polar meds that my deep deep love for this man just vanished overnight. I still love him in a way, but it’s like he’s my best friend, like a brother. We’ve been together so long and done so much together. I care about him so much as a friend that it’s killing me to hurt him and tell him how I am feeling. Please please tell me this will go away! Please I am desperate to know I will love him again. I am now down to 150mg per day of Effexor and I am not emotional in a general sense but just about this one issue. Sorry If I am rambling and all over the place but I just don’t have the words to say how lost I am in this situation.
