Know this is a pretty frequently discussed topic on here and a lot of good advice is given so here goes.
Been suffering from depression for years and I'm currently going through one of those stages where I'm just constantly feeling shit no matter what I do and am really struggling to get up in the morning to go to work and can barely go an hour without having a suicidal thought, took an overdose of pills last year but that didn't work and in all honesty I feel like I did around that time, but don't really have the bottle to try owt like that again. Know fine well that I don't help myself in some aspects but just want to get to the point where I can live a relatively normal life.
I'm not especially close to my family and whilst I do love them I can't really bring myself to confide in them, been fucked about and fobbed off at every opportunity by the doctors whenever I go to see them about it, I do know that I can always tell my best friend but I don't want to bother them again with this shit, especially after a little drunken heart-to-heart we had last night, so just thought I'd give this a go.
It is frequently discussed on here, as you say, because so many people suffer or have suffered from it, myself included, and often dont talk about it.
A couple of thoughts that I would add - the first is that if you are having suicidal thoughts, you aren't safe. Please go to the GP and tell them that. Make an appointment today, it will be the start of you taking control over this thing. I'm not sure what you have told the GPs previously, when that was, etc, but my experience was massively positive when I spoke to my GP. Almost immediately I'd made what felt like the difficult decision to talk about it, I felt like I was taking small but important steps to take control. It's unfortunate that you have been fobbed off, I was too many years ago, but when I was really honest with them about how I felt, they listened. There is a lot of support out there which GPs can signpost you to.
Don't beat yourself up about this being your fault, or you could do more to help yourself, etc, etc. You have an illness which needs treatment (of some sort). We could all do more to look after our mental health, of course it would be good to exercise more, drink less, etc, but you have an illness. I really think you need to get into a safe place first, before you start to focus on some of the positive changes you can make.
It's great that you have a best mate who you can talk to about this - I can certainly identify with what you say about this being hard to talk to your family about. Thinking of yourself as a burden is a common depressive feeling. I'll just ask you the question - do you think that your best mate, if he was to know you were feeling suicidal, would want you to talk to him about it so that he could look out for his best mate, or regard you as a burden? So if he doesn't think you are a burden, don't put that label on yourself.
All the best, if you want to PM, please do at any time, as a lot of what you are talking about resonates loudly with me. But most of all, take that simple but massive first step today of seeking help. Then you begin to fight back and regain control of your life, day by day. And when you do, it feels great.
