Ditto to the above. Having a safe or anonymous space to explore and express your feelings and consider coping strategies can be helpful. Whether that's the formal setting of counselling or the informality of online stuff, just that chance of bringing thoughts into the open to better examine them is a good starting point. I'd recommend the formal setting for your own privacy and safety.... Uni counselling /support services are probably the most easily available. But more informal stuff can be a good back-up, just so long as you are aware that the people you speak to may have motivations of their own, and not necessarily benign.
