How can i help.my girlfriend?

My girlfriend has been in a negative mood due to her getting laid off, she feels like she messed up her life due to finishing school later in life rather than right when she got out of highschool. She recently moved out of my apt because she wanted to be inedependent and have the experience of having her own place. Btw she is 29 and has never lived alone so now she is considering us moving back in togeher due her getting laid off,but she I really feeling low abt herself because it seems like she is uncapable of living on her own. This is now affecing our relationshipp she is not her ususal happy and cheery self and her libido is way down due to the job situation.everytime I tell her I will help her with her bills she gets frustrated, because she says its a reminder that she can't do it alone so how can I help her get her self esteem and libido back
