Maid of Honor Drama

My maid of honor just called me sobbing. She said she is really stressed being my maid of honor. I haven't really discussed wedding planning with her other than talking about bridesmaids dresses which haven't been purchased yer. She had mentioned a few weeks ago about my shower and bacherlotte party, but I didn't really say much since my wedding isn't until July. I know my mom talked to her once about it, but hasn't heard anymore. I know she is a maid of honor in a wedding about a month after mine so I am wondering if that is stressing her out. She tried telling me she feels like everyone is going to pay for a bunch of stuff and she doesn't have the money. I tried convincing her that all I care about is that she be in the wedding. I don't really need her to pay for anything. My mom planned on hosting my shower if no one else was going to so my mom would be thrilled to handle that. I don't drink so I don't need a fancy bacherlotte party and I was honestly just thinking a pajama party with junk food and romance movies. I guess I don't understand where all of this is coming from, but she indicated that she doesn't even really want to be in the wedding a lot. The other thing that has been weighing on my mind is that my brother's wife has gone above and beyond to help me with the wedding planning. She has gone with me to appointments. She has sent me ideas for stuff. She was going to do a reading at the wedding, but I know she would love to be a bridesmaid rather than doing a reading. I have been on the fence about asking her to be a bridesmaid rather than a reader. Do you think it would be wrong to ask her to be a bridesmaid instead of doing a reading?
