hi mango_flower
so sorry to hear that you are so unwell. If you are used to her looking after you as well as you describe, then it's understandable that you will miss that care terribly.
I don't believe that being upbeat yesterday was an illusion. You will have good moments and days and for a time they will be followed by gut-wrenchingly bad days. It's reasonable to expect that having been raised up and the dropped from a great height it's going to take time to get back onto an even keel.
I got annoyed with some family members last night who were pushing me to move forward - I don't think it's unreasonable to not be totally healed, well and ready for another relationship after the breakdown of a long-term marriage and years of recycles, mixed messages, incredible highs and dreadful lows. Five months is nothing. I know they are anxious in case I still feel an attachment to him and just want me to be happy but I just end up feeling like a failure for not being there yet.
Even if you've been in a short term relationship like this, it will mess with your head (and your body, your finances and your other relationships) to such an extent that it's possible to take a longer time to recover than the amount of time you were actually a couple. I'm not trying to depress you - just ask you to be gentle with yourself.
Another post from me (sorry)
And don't apologise for posting! If nobody posted, the board wouldn't exist and I for one would not realise other people were going through something similar.
