I'm so sorry to hear about you losing your job. Your mum is highly wrong for telling you finding a job is easy, I KNOW how hard it is, as everywhere is either looking for jobs left right and centre, or there is just generally no hope in your area whatsoever. Please talk to someone about this, a friend, a GP, or a therapist. There's always help out there, please don't lose hope. Nothing lasts forever, I promise you. I completely understand your frustration and get why you feel like this. I can't imagine how awful you must feel, but you have to push through it. There are always going to be times you feel like you can't do this but PLEASE push through this. You CAN do this.
