What degree are you doing?
Don't think that "because you haven't made friends" your time in uni will suck. There are thousands of people with all sorts of backgrounds, likely, some in a similar situation to you who you can still meet. University, unlike school offers social freedom, that shouldn't be a concern.
Just chill-erino. Meditate or something. Join a yoga class. Stop overanalysing the sentiments from your tutor & teachers and try to re-evaluate what you are capable of doing and not capable of doing to resolve any missed deadlines.
Its only the first year too, remind yourself that it doesn't count for much but should be a strong guide and platform to build new habits for the harder years.
remember, these difficult times, regardless of their context or circumstance allow us to shape stronger future habits and ambitions more than ever.
