I feel like if I keep posting it will have me still thinking about her and I really want to just erase her existence as she did mine and totally forget about her as she did me
It can be like that, if you don't post then simply reading can help. I had to wait till I was over 6 months out before posting but had read lots up till then. If I read my posts from the early breakup I think they would upset me now. I've deleted everything I've wrote or received from her. It was the only way. Have a read at the staying side of the forum, it helped me detach knowing what awaited me in the future had I kept her. Good luck I hope you are feeling better very soon. Don't worry too much about the timeframe for healing either. I did and it only caused me more self inflicted pain.
