It is ok that you are struggling against a tide of anxiety that is reaching tsunami proportions. This doesn’t mean you are losing the plot; it is just an expected dip in your recovery.
I know you feel disappointed in yourself as you really thought you were fixed and that the drugs do work, you thought you were yourself again. You are yourself; you will be even more yourself again soon.
Please don’t beat yourself up for wanting to run away and weep, this too shall pass. The light at the end of the tunnel is not an oncoming train; it’s your daughter with a torch.
