Lot of disappearing songs in library

[Othli]

Hello,

I had recently recently issues with disapearing playlists (that I recovered from the website a few times) and I suspected someone using unwillingly my spotify account so I disconnected from everywhere and change my facebook logging infos.

but not much later I noticed that Now a LOT of my songs disappeared for my library (not playlists) like entire sections of songs recently added or not (my very first songs (bottom of the list) are gone and I remember exactly what were those songs) they are now just gone from the list as if I never had added them. 
This is on every support both computer and phone and Its really annoying as someone with as many song to have to recall everything I had and Re-add them. 

Is there a way to resolve it and get back all the songs that went missing in the last month and to resolve this bug ?

This happens to me ALL THE TIME. I still have the first songs that I have downloaded but I am missing bits throughout my saved songs list. SPOTIFY PLS HELP! Its very hard to remember names of songs for me and I download many of my songs from Discover Weekly...
