Have you talked to your T about what your dad says to you and the effect it has on you? Do you have an eating disorder? that could cause alot of the physical symptoms, but depression will do this too. If you take the meds, they will even out all the days, so bad days are less painful. If you don't like the meds, you can stop them, but do so with the T's support because you have to wean yourself off them. Meds have helped me alot, I am still having bad days, and my meds could use some tweeking, but better.
