worried about my current relationship.

hello.
this is my first day on nofap and im excited to be on this journey with others and know that im not alone in this.
i have been dating this amazing girl for 2 months and she is everything i look for in a partner. shes funny and geeky like me, but she is asexual.
for those who dont know what that means, she doesnt have sexual thoughts or cravings like other women. she pretty much has no sex drive and i was okay with that.
to my shame i was okay with it because i was watching porn and engaging in porn games and even a porn MMO.
i was watching porn many years before i met her, and since she is asexual i guess i have the need to fill that sexless void.
then i decided she was worth quitting for.
i quit last week cold turkey.
all of a sudden i was feeling unmotivated, my anxiety shot through the roof.
i felt depressed and at times had suicidal thoughts. but had the good sense to not entertain or act on those thoughts. its taken me about a week to realize that this might be the root problem. i thought it might be commitment issues and many more thoughts along those lines, but this makes the most sense because i didnt have these thoughts and feelings until i quit porn completely.
since i learned about this site i have felt a little bit better knowing im not alone and i can get the help i need. for my relationships sake.
i really do love her but this feeling is overwhelming and almost destroyed us. but i refuse to let that happen. because i know these feelings and thoughts are not going to last forever. i know she will put up with me but for how long i dont know.
id love to talk to anybody with similar issues. thanks for listening to my story.
also should i tell her about all this?

 

Thank you so much.
Means a lot to know i am not alone in this like ive said before. Some if not a lot of my anxiety comes from telling her or not. If she accepts who i am and supports me through this im sure to feel a lot better. im sure of it.
