Hi Jane
A warm welcome to the site and you've already said it yourself it is very early on in your recovery so your emotions will be all over the place for a while yet. Short term memory problems and fatigue are very common in the early stages of recovery. Just remember be kind to yourself and rest as often as you need. It is very tempting to try to overdo things that usually results in a few bad days but at the same time we are only human so are very prone to pushing ourselves to the limit and beyond.
Take care and look forward to hearing more from you.
