Turning it on and off like a switch

How is it that they have the ability to turn it off and on like a switch whenever its convenient for them. Its always on with me. Near his family (which is once in a blue moon) its off. Why me. Im the only one who tries the hardest. I might as well be banging my head against the wall. I just started taking Zoloft first time last night. It took the edge off but I wish I could take more. Have to talk to my dr. first. I wish i didn’t take him to see his mother. I wasn’t thinking. He hasn’t seen her for at least 1 1/2 years. Before that whenever he saw her he would get worse seeing her deteriorating. He wasnt doing that greqt to begin with… …but if he didn’t see her and something happened he would still have major problems
