welcome to the GPGTools support platform. Sorry you are having problems using GPG Suite.
This KB article explains your options, in case you lost access to your secret key or password.
Take your time to go through that KB article, especially the section about Lost access to secret key or password. The other important section is 3. Revoke key: "If your key was created with GPG Suite 2015.06 or later, a revocation certificate can be found at ~/.gnupg/RevCerts. In that case revocation is easy." That section has exact steps how to proceed in that case.
