ahh sam, you are not doing anything wrong. the frustration about being sad, is another thought, so you observe this too. the frustration of 'doing something wrong, or 'not getting it' are also just other thoughts, so you observe these too, without trying to describe or analyse them. i don't mean 'just' in a dismissive way. you just try keep coming back to this again and again, whenever you remember too, there is no pressure. the aim is not to get rid of the thoughts you don't like (annoyingly!), though they might go. the aim of meditation is not to find bliss or happiness (unfortunately!) - or to find a set a circumstances, thoughts or feelings to hold into place, so you don't feel sad, or you don't feel any negative emotions. it is about finding stability within all of the emotions and circumstances that might arise. no, not 'finding' stability, but recognising that you already have that within you, , regardless of what thoughts arise. it is all a bit abstract. I get overwhelmed by my thoughts all the time, though talking about it like this, helps to remind me, for a short while at least. try a meditation class, or chat with your GP about referrals like paula suggested.
