Westendtown I can hear the desperation in your posts and wish I had an answer for you that would magically make things better. I have suffered from mental health problems for decades, mainly anxiety and panic attacks, and this lead to depression. I often felt like the medical professionals didn't understand how bad things were because I was never suicidal, although I would often feel like my life had no point. Sadly due to lack of funding and availability, mental health care rarely seems to be able to meet people's needs, a lot of the time it seems to be fire fighting and literally just dealing with emergencies and then once a crisis is over there doesn't seem to be enough support to keep any improvements made going.
I can only tell you what has helped me, but it may help you a bit. This year my partner of 3 decades left me as he could no longer cope with my issues. This absolutely devastated me and meant my life changed totally. I had no choice but to contact my GP and beg for help. I was also able to self-refer to a mental health programme. I am lucky that I have a lot of family support, do you have anything like that? My GP prescribed me a few clonazepam to take very occasionally at night if I was really struggling with a panic attack, that did help me calm down enough the few times I took one enough to get a few hours sleep. Sleep really did help me feel a bit better. They also got me to increase my anti-depressant dosage. The GP referred me to a mental health nurse that is attached to their practice. They spoke to me and suggested a few local mental health projects that might be able to help me, as well as emergency organisations such as Samaritans and again some local projects, that would be able to help me during the night if needed. They also referred me to a peer support worker through Mind who I am now seeing every couple of weeks just for a chat- which really helps as we share experiences which makes me feel less like I am alone, but that also what I am experiencing is actually not that unusual, and that people do get better.
I am also autistic and find a lot of the general life things hard that the majority of NT people seem to find easy (or at least it looks to me like they do!) like being tidying, being organised, not getting overwhelmed just by daily living etc. I am learning that planning is very important to me, also having a plan - even if it is for something really basic makes me feel more in control, and therefore less frightened and anxious. So for example I really struggle at night time, so I have several activities that I can do if I can't sleep that are fairly easy, but distracting enough to hopefully engage me until those feelings have subsided a bit. For me that is knitting, jigsaws, maybe reading if I can focus enough, or watching tv that makes me feel safe.
I have a list of tasks I need to do for each day, but I use this as a guide, and try not to get stressed if I don't complete all the ones I want to. Some of them I do everyday and tell myself they have to be done. Those are things like getting washed and dressed. Brushing my teeth, making sure the washing up is done. Other tasks might be leaving the house even if it is only walking up and down the road. It is all a work in progress, but I guess I'm saying what lots of other posters have said which is you will have to take ownership of some of the things you are finding difficult. There is help out there, it might not be perfect, and it might not come from where you think it should, but there are ways of creating some of the support you want.
As previous posters have said supportive housing for people with mental health difficulties is often not very nice. It can often be very noisy, the people you are sharing the building with can be intimidating if their issues cause them to be loud or aggressive, and from what you've written I think that sort of environment would make you worse.
Another poster asked, but I couldn't see if you'd already answered, but have you contacted Student Support Services at your university? If not they would be a good place to start. Or go on Mind's website and you can search to see what services they offer in your local area.
