feeling shitty

My fiancé and I are extremely poor right now. We've had some crazy financial struggles. I just want to do something nice for him and take him to dinner. He has been so crazy supportive. He has stood beside me through my battles of Bipolar disorder, ptsd, anxiety, and being in the hospital because of it. It's killing me that I can't do something for him. I can't even make him dinner because we don't have the supplies and I can't focus long enough to cook. He keeps telling me that it's okay that we don't get to go out but deep down I know he misses the luxury. Honestly it makes me feel terrible and I just wish I could find a way. I've thought about selling some stuff but I don't have many things. And platos closet won't buy my clothes because they aren't designer. It's heart breaking wanting to do something for the one you love who has done so much for you, and not being able to.
