Feeling down in Life and love

So I’m trying to be a supportive, loving and caring boyfriend. My girlfriend has anxiety and a lot is going on in her life, I’m trying to give her space to deal with stuff but yet trying to be there when she needs me. Although the last few weeks have felt distant, when we’re around each other it’s great and then when we’re away it’s almost as if we’ve never met. Texting has came to a stand still, it seems as if I have to jumpstart every conversation, which makes me feel like I’m just a nuisance. She has appologized for not being as chipper as normal or active in our relationship. Part of me tells me to hang on because I know if she can pull through this slump with me being there for her, then we’ll be closer than ever. But the other part of me has doubts and is more scared than ever if the possibility of losing her altogether.
