I wouldn't be hurt or offended by these gifts at all but I would rather a friend bought me a gift related to an interest of mine such as my favourite game, film etc or a cute gift made by them such as a frame with pictures of us in it. I would get this kind of gift for someone out the blue, not as a special occasion present like for a birthday, Valentines etc. It does show you care which is the main thing and the thought definitely counts but I can imagine some people (I wouldn't but I don't know your friend) would maybe see it as a reminder that you see their illness before you see them and their interests,especially if they have anxiety issues.
