You’re not a “nuclear bomb”, or you wouldn’t be asking that question the way that you did. 
If you are finding your intentions are getting twisted and the results are not what you wanted, that could be negative attachment or a curse getting in your way. Doing magick attracts these things as much as negative emotional energy in your life, so as a basic practice you want to be taking care of your spiritual hygiene the same way to take care of physical hygiene.
As a basic precaution I would recommend starting with a thorough banishing and cleanse yourself, your space and your whole house, also your car. When cleansed you should have a clearer view of influences you need to get rid of that are interfering with you.
We have some free resources for learning how to do basic spiritual hygiene.
