My old t have me a huge gift before I moved. She knew we were struggling and needed help to make the move. She called it a late wedding present (a month after I got married), and told me not to have my dad help us move (he's a huge trigger for me). She had given me the card at my last session, but told me not to open it until I left. I cried when I saw it. I called her and thanked her. She said to do something similar to the pay it forward idea...
Maybe you can talk to her about it making you feel weird?
