This is more of a vent, so I apologise for the wall of text.
I [m19] started sixth form in September 2021 as an external student, after attending a grammar school for secondary school but being rejected because my GCSEs weren't good enough ( despite not sitting the exams). I was heartbroken by this, but more gutted at the fact that I would have to leave behind 3 of my closest friends.
Although I started sixth form with hopes to make friends and move on, my mental health plummeted. I made one friend in the first week, but he found a friendship group and we never spoke again (which I have no animosity or problem with). My biggest issue was my incredibly subpar social skills, and it still is. I don't know what exactly is wrong with me, but for some reason I just can't verbally communicate properly with people (outside of my family). I can muster up one or two word sentences, but that's it. I struggled to approach people, let alone hold conversations with them. I always sat in the corner and pretty much isolated myself, and I was the only person in the year group with no friends at all. As I progressed into Year 12 and eventually Year 13, this worsened. I became incredibly avoidant and somehow scared of everyone in my year group, and as a result, stayed away from the sixth form area and isolated myself in the library. I don't know where this came from, but I felt constantly paranoid and restless when near people. Being isolated eventually stemmed into suicidal thoughts and depressive episodes, which I also suffered in silence.
My head of sixth form found out that I was struggling with suicidal thoughts because I quite stupidly searched up "How to deal with suicidal thoughts" on the school computer in a lesson, which was traced back to me. I struggled to really say what was wrong with me, just that I was lonely, tired and just struggling. As a result, all they offered me was referring me to the school counsellor. I did attend about 2-3 sessions, but they were not beneficial to me at all - instead the sessions made me feel worse.
This in turn also affected my grades. I was an A-B achieving student at the start of Year 12 and I wished to keep it this way, but I just couldn't focus on anything at all. I would bring myself to revise, but couldn't - as I would just get distracted by my thoughts - ironic because of how much time I spent in the library. My predicted grades were also very poor ( C, D and Merit) which shattered my self-confidence even more, and so I didn't apply to university, and instead planned to take a year out.
I also revised very little for the A-Level exams itself at all - at this point I was numb and tired of everything. I achieved the exact same results as my predicted grades, but at the time I didn't care and was just glad I didn't fail anything.
After taking a year out (and doing work experience, but nothing else), I applied to university, and that brings us to now. I applied to a local university because my grades weren't really good enough to move away anywhere unless I took a foundation year - which I am not keen on (I go to BCU, if this is relevant) . I regret not moving away, now, but I can't really drop out. I made a post on transferring also, and I am beginning to email the faculty/student support, aiming to get a transfer for the next academic year.
I don't know why I am the way I am, nor do I even know what is wrong with me. I have suspected Avoidant Personality Disorder simultanously with major Social Anxiety, but I haven't recieved a diagnosis, so I can't comment for sure. My social skills are still very poor, and I understand that exposure therapy works best, but I am just too anxious to try it, and even when I do, I feel worse after socialising. I am still lonely at university, but I don't really care anymore.
I recognise that I do need help, but I just don't know where to start. I'd really like a diagnosis at least, but my parents unfortunately don't believe in mental illness and have enough problems of their own. I don't even know my own GP nor how to contact them.
I just feels incredibly isolating and dejecting to feel that nobody out there went what I went through, or know what I went through. I never had my feelings validated either, even by the school counsellor. I try to move on, but it just feels that all the isolation and non-existent self confidence has somehow scarred me permanently. I just don't know how it's going to get better for me socially or mentally - if I struggled in forced proximity, how will I cope as an adult? How will I cope for the rest of university? I do try to put behind everything that happened to me, but I always spiral and suddenly I'm the 16-17 year old loser in sixth form, unable to fit in.
I would really appreciate if anyone can offer advice and support on what I could do to stop feeling like this, and to get better. I understand that it will probably be a long process, but I'm just tired of feeling like this.
[tldr- isolated and depressed in sixth form. got **** grades, and unable to move on as it has still impacted my self confidence, and still socially inept]
