I suspect not? :/ I'm nearly 18 now, and in August this year (so not too long ago) the Police detained me under Section 136 of the Mental Health Act because I'd completely broke down and lost it that day, mentally. I was basically detained for contemplating jumping off a multi-storey car park, although I never actually threatened it. The police were called because the guys monitoring the place via CCTV called them and told them I was going to do it. I was taken to a police station, put in a cell with an officer babysitting me, and had a mental health assessment six hours later, which I then went to hospital voluntarily for 3-4 days to chillax and keep safe. I don't at all have a criminal record, but this is certainly on my medical records, and I fear it's put the final nail in the coffin of ever joining the armed forces? I'll also be honest that I also used to self-harm a lot when I was 16, and I had visible self-harm wounds from when I was detained as I badly cut my left leg that day on purpose, which were also written down in my medical records, so I could never lie about them even if I could. I'm also on a mood stabiliser (Lithium), but I won't be on it forever. I've always liked the idea of joining either the Army or the Navy. I have a few relatives who were in the armed forces, and I love military movies, and videogames. I used to be in the Army Cadets for a while when I was 13 and went with the school to an Army careers thing. I've wanted to either join the Military Police, Royal Artillery or be a CMT. Or in the Navy, be a Navy Diver or work with the aircraft. I was planning to enlist in the armed forces when I hit 16 and finished my GCSE's, but ended up staying on in school for Year 12, and now I'm at college studying Science and plan to study Biology at university after my degree and do something related to that as my second option. I know that the armed forces is not really a mental illness-friendly field of work due to the fact it's highly stressful and there's dangerous weaponry around, so I could understand why they would not take the risk with someone who was knowlingly once suicidal. But I'm just wondering if this is a permanent disqualification, or whether I could join in a couple of years when I'm about 24 or 25 and proved mentally fit through Occupational Health, etc? Sorry this is long, and please don't flame me or judge me. But do be honest with your replies and not sugarcoat them. I'm not going to be surprised if it's a big fat no, I just want to know if there's a chance, really. Thanks for any replies.
