Oh Onit, I am so sorry, and you are not alone...
I recently had my final session of 6 NHS free sessions with my counsellor.
We agreed a list of simple, not very taxing things, that I could try to do as often as possible to make sure I do something for me. Nothing grand like yoga.... you can search for "boring self care" for ideas..
She gave two helpline nos . for C.A.L.L (not sure if that's just a Welsh hotline) and the samaritans, and names of three friends I should call if things really become too much...
Please reach out to your dcousin, to us, to your friends, if you feel overwhelmed...
It may be worth doing an "anyone up?" chat on mumsnet if there are no other options..
Be very very very kind to yourself... you are not a fraud. Do what you have to do to take care of yourself. Be as kind to you as you would to your dfriend or your dcousin xxxx
