How can I get my inheritance

Please accept my condolences on the loss of your relative. As for your question: If your cousin is nominated as Executor by the Will but the Will has not been offered for probate, then your cousin is not the Executor. You are only an Executor once a Will has been admitted to probate and the Executor appointed, sworn in, and issued appropriate paperwork. If you don't think that your cousin is going to be a good choice to handle the estate, then you may be able to challenge his nomination as the Executor. You may also be able to petition the probate court to compel him to produce the Will if he has not yet turned it over to the court. Contact the appropriate probate court and make sure whether the Will has been filed or not; if it hasn't, then you should contact an attorney and have the attorney help you with any further court actions to compel production of the Will or challenge the Executor's appointment. These are not good actions for self-help. Best wishes to you.
