A fellow Mechanical engineer who just graduated right here. I completely screwed up the 4 years of my Engineering feeling about how you feel right now. Result I had average grades, worsened stutter, no network,no job and also... no relationships. The things I would suggest you to do which I failed to do are: 1) Never hold back any academic doubts in the class due to your stutter. 2) When presented any opportunity to speak in front of a class be the first to grasp it 3) If 2) goes bad and you feel like never doing this again prepare better and do the same again. 4) Use every opportunity to network. 5) Don't lose your passion for engineering. Keep learning new skills.
