Oh limon, I hear how tired and fed up you are. Depression and anxiety is so awful, so draining, so debilitating.
Firstly, you have already identified that the terrible thoughts come from your anxiety. They are a symptom of an illness you have, they are NOT who you are. If you can, when you have these thoughts, try to put them in a box in your mind, a box which is SEPERATE from you and is for the symptoms of your illness.
You are not your illness. You are not Anxiety. You are not Depression. it is so hard to separate these thought, I know, I live with anxiety and depression too and sometimes the intrusive thoughts are crippling. But I work really, really hard to try identify which thoughts are a symptom of my illness and which are actually justifiable.
Without making this too much about me - some of the thoughts I have are similar to yours, my kids would be better off without me, everyone at work thinks I am useless.
A frequently occurring one is disguised as a positive thought and it says to me "the best plan from now on is not to bother with other people, just bunk down and focus on you and the kids". It took me ages to realise that this isn't about the positives of focussing on my kids but my anxiety and depression trying to isolate me from the rest of the world. I frequently decide that the best plan going forward is to not contact friends (they don't like me anyway), not bother going out (what is there out there?), not let anyone in my house (they only judge, right?) etc.
Do you think your meds are working? I took Citalopram for a while, not convinced it did much. I came off it because I thought it was making me gain weight but haven't replaced it with anything - I also have major issues with procrastination so haven't been to the doctors in a while.
Does writing stuff down help? If you have a negative thought - e.g. "Something is going to happn to my daughter" - write it down, and then try and identify where this has come from, e.g. "I feel like something bad is going to happen to my daughter. This is my Anxiety talking." Have you tried CBT? That can be helpful for identifying types of thinking and how to try and reprogramme the unhelpful ones.
I understand. I was awake at 5am panicking about money.
You are not a horrible person and chances are people don't hate you. You are ill, you have depression and anxiety, and with illness comes symptoms which can be hard to manage. But you do not have to define yourself by your illness.
