If you don't enjoy anything in mechanical engineering you should probably choose a different major or course for your life, if your college is cheap (if you are in India that probably isn't the case anymore) it is only another 3 or less years (maybe less if you change into civil or another engineering that has similar pre reqs). But if you enjoy a few subjects, like maybe vibrations or controls or mechanics, it might be worth it to stay and just apply or work your way to a job into that category. I lost motivation in my ME classes as well and the best thing I did was cut down in course load, it gave me a break and was well worth it for an extra semester added on to the degree. Other than that engineering coursework sucks, you do it because you like learning and you like solving problems, sometimes it takes extra time and sometimes you burn out but if it is what you want to do you keep at it. Just be aware that a single internship isn't necessarily what a job will be like. I don't know how much help that all is but maybe something good will be in there.
