there will be times when that will happen. i know what you are feeling just try to think of that one feeling that made you super happy and just keep thinking about it. mannifesting stuff deosnt have to be with great emotion certainly it does pick up the pace but if you think about what you want vivid like visualizing yourself with that object that you want and just feeling what it would be like to have it then it will eventually happen you just have to stick with it. Dont let negatives get you down thats what it sounds like is happening to you. Think positively and you shall receive positive outcomes
