Needing some mindfulness tips for myself

I'm going through a difficult time with a care package I'm currently receiving for my own health issues I've lost my way due to being treated mentally and emotionally like I'm nothing I'm struggling with worthlessness and being a burden and bitterness towards neglect and being left to suffer in that situation and hate towards me for being so physically unwell I've been treated this way since 2014 messing with my feelings towards myself I've lost trust in the home care given I just want to work on mindfulness strategies to try build myself up mentally for another care package .
