If you have any anxiety add ginger to your diet. (Candied ginger, ginger kombucha, boiled ginger with lemon/cinnamon or honey...list goes on) It gets rid of the nausa associated with lack of sleep or anxiety.

I think this also means you need to have a heart-to-heart with your mom. It sounds like you want to express things to her and talking is a great way to do it. Then its our responsibility as an individual to cherish and be present with the individual. Its never too late to extend a hand.

I have a feeling that confronting the anxiety source will allow you to rest again. Finances and stuff can be dealt with when the time comes.
