Lucyvoid's journey

I'm currently in a tough situation, dealing with a cheating fiancé and lacking family support. I work full-time at a store, but I'm looking for a second job to help make ends meet. I've applied to several restaurants, but my options are limited due to my history of heatstroke; I can’t work in hot environments. I have a high school diploma and I'm wondering what other jobs I can apply for. I'm open to getting certified for something that can be completed in under a year and offers decent pay. I just need to find a way to provide for myself and my animals, as I'm exhausted from the constant struggle and feeling stuck.
