Nursing, no money, no friends.

Where do I begin. 😞 Started my nursing course beginning of the year and honestly having the worst time. I don't mind lectures and the theory side but practice is horrible. Literally makes me depressed. Hate every second, I get parred off with the shite jobs, the nurses do not bother with students and tbh I'm just not enjoying it. The thing is I don't wanna leave as it's only my third semester and things might get better but I doubt it, i applied because everyone else did and have never really had the drive and push to do it. Along with not enjoying the course I feel as though I'm not even at uni. I have NO friends and trust me I tried and tried to make them but everyone already knew each other and I just tagged along 😞😴! Also the friends I do have are not at uni and all work, they go on holiday, go for meals, go on nights out. I HAVE NO MONEY. I get £150 a month off the bursary which is not even enough to eat on. It's just depressing I am really in two minds on what to do. If I leave I have nothing to fall back on. If I stay I'm gonna be depressed and broke for 3 years. Please help! Has anyone else been in this situation.
Oh and I did have a part time job but working 40 hours a week on placement and having a job is near enough impossible 😞
