Hi. Hope You Are Fine. I Suffer From Anxiety And

Hi. Hope you are fine. I suffer from anxiety and migrane and sometimes I get convulsions all over my body. I take some medicines and situation is under control but they sometimes lower my blood pressure and make me feel dizzy. I am considering blood donation and this is my first time. Is it safe to do so. Is there any chance that it may increase convulsions or make me feel too dizzy to work?
