I get where you're coming from, I was of much the same mindset. However when I realised that because I was feeling so rubbish, I was starting to avoid spending time with my children, bursting into tears for no reason/over stupid insignificant stuff and generally crawling through the day on some kind of auto-pilot I knew I had to do something.
A low dose of AD doesn't stop you feeling anything, I have days where I'm a bit down, but I'm now able to see that it won't last, that I can do something about it. They've also helped me be far less 'stressy' - when I was having a lousy day pre-AD I would lose it with the kids waaaaayyy too quickly, and get irritated by minor squabbles and so on (I have 3 boys). Now I'm able to stay calm (most of the time!) and not go bonkers over the inevitable squabble about who sits where in the car etc....
To give a little more background as to my decision to go back on them, I've had a run of ill health with my youngest DS which caused some major friction between me and my EXH (put a stop to that with a firmly worded letter reminding him of the contact agreement we had and his responsibilities towards the children - looking back I now see that he was EA to a degree), I'm currently unemployed and struggling to find work that I can fit around my family, my dad has terminal cancer, my mum whilst significantly recovered from her illness is finding things hard going having her lost her mum earlier in the year, worrying about her dad and of course supporting my dad and as my brother and his family now live 2 hours away, I'm the one taking dad to hospital appointments etc (my brother's business also went under at the start of the year leaving him and his family in a precarious position for a while). Since being on the tablets again, I feel far better placed to deal with the above, and as such am able to enjoy the good moments that come in amongst it all, and recognise that some of it is undeniably horrible at times, but not entirely insurmountable.
As my first health visitor told me 11 years ago, sometimes you have to put yourself first and make sure you're ok and looking after yourself, after all if you're not, then you're not able to be there for those people that need you, namely your children.
for you.
