Sewing machine blues

My step-dad is a karate instructor, he asks me to remove old patches and sew them onto the new jackets he gets. This most recent time has thrown me into a very deep depression. Some backstory..backstop... I lent one of my roomates my sewing machine to fix up a hat of his. I briefly showed him how to use it and then warned him that if the material was too thick he would have to sew slower or hard stitch the item. He did not listen and broke 2 needles off in my sewing machine. I thought I was out of replacement needles and I haven't used the machine since then. My wonderful husband replaced the needles and today I needed the machine to sew the patches for my step-dad. I honestly feel as though this is one of the only times we can connect, is if im useful. I hate disappointing people... anyways the machine kept snapping the thread and wouldn't work to actually sew anything. I was trying to troubleshoot the problem and it turned into a depression spiral. Again my wonderful husband ordered a replacement piece for me and I ripped my roomate a new one for breaking my machine... im unmedicated and suffering.
