Hi Nitaf - I've been on the road these past few days, sorry have not looked in sooner. Just a few thoughts from my own, current experience.
Crying bouts are ok, be prepared that these will happen, anything can trigger them, and they can last a while. Have a pick-me-up strategy, and just go with the flow. This is NORMAL
I totally agree with Meredith, you will need to call up your courage, and enforce boundaries that you have set, because these are important to you. Being less available is ok. It does work.
NG responds better to me when I am upbeat, positive, and convey a sense that whatever he did, we WILL recover. It is like he needed my confidence to help him find strength in himself.
Seconding Meredith again, where are the goals, Nitaf? Maybe reviewing positives at the end of the day? Little things, frequently, are best to keep the ole PMA up.
You are strong, loving person, you will be ok - Slowly
