Trying to return support

Within two weeks of coming out to her, my mum offered to take me shopping for more comfortable clothes. I was so thankful that she was being so supportive and really wanted to show her that. I tried so hard to be in a good mood but it was really stressful. My bandages kept coming undone around my chest and my hips were making it hard to find fitting clothes and I ended up breaking down and shutting off a bit. I feel so guilty because she made a huge effort to help me be more comfortable and I feel like I ruined it.
