Hi. You are not beyond help.
It sounds like you need the opportuni to learn some strategies to help you, especially on difficult days. Would that help? Like tell the Cpn that weekends are hard, or particular times in a week for whatever reason. Tell them what happens, what you think and feel. It is not necessarily needing more or different support but in using what you have to help you manage how you are maybe. There is not always a magic wand, sadly. It could be Something like identifying difficult times, working out what you can do and what you need from others - eg. List of people you can call, family/friends/Samaritans etc before you then call out of hours gp or go to A and E for assessment or referral to crisis. As well as what self help activities you can do that helps.
Just jotting down some of the things I have learned to help me. I saw a very sharp, quite forthright Cpn for 8 sessions once ( not under a CMHT long term) who helped me realise what I could do, what I could not do and how to manage. It was not easy, admitting where I needed help, gp whether I needed outside agencies or if friends/family would step up etc. but it got me through a very tough time. And sometimes just knowing what to do was enough, I rarely needed to do it.
Being honest is often a start. And accepting at unless there is a wonder medication yet to be tried, that it can be trial and error and that it is a process, taken step by step. You are in charge, responsible but may need extra help at times.
Sorry. Feel free to totally ignore anything I write. It may be totally useless or irrelevant so please I am not offended, just ignore.
Hope tomorrow is an easier day for you with some nice distractions.
