OP I understand you and I'm sorry you've been through so much. Yes, I noticed it too, that a lot of people have no empathy towards people with mental health or even physical disabilities, especially if they can't work because of it and need to be on benefits.
You can check the threads about PIP where claimants are in wheelchairs and they aren't given the mobility rates because they can "move around" in mobility scooter. Or because they have prosthesis leg, they can "move around". It's totally unfair in my opinion how some PIP assessments are made.
The reality is, attitude towards people who have physical disabilities or only mental health issues and can't work because of it, is the same, most people don't understand and don't care about it. They don't even care to try and understand it, especially the government and DWP.
I would actually suggest to all those people, the next time when they feel really sick with cold not to stay home but to stand up and go to work. Maybe after a few days of working being really sick, they'll get it, why people with mental health issues or physical issues can't work and need to be on benefits. Although I bet most of them won't manage even to get up and arrive at their workplace.
I think the problem is that people can't understand how it feels something what they've never been through. They don't understand how because of C-PTSD you can't function at all. All they see is "free" money, instead of realising that everyone would prefer to be healthy instead of receiving this kind of "free" money.
It's the same with the victims of domestic abuse, where the victims are blamed instead of the abusers. People who have never been through it, don't understand why the victims stay for years. They don't ask questions with horror why and how abusers can do such horrible things to their victims? How society can stop them? Instead, they ask the victims why they didn't leave and didn't protect themselves?
In your case, being a victim of sexual abuse in childhood is terrible. I can't even imagine what you've been through, but you have all my empathy. I think you've done great after what you went through to carry on living instead of giving up.
Don't listen to people here or in your life who don't understand you. They are either ignorant or abusers themselves. For real, what kind of person will blame you for not being able to work and function after you've been sexually abused in your childhood? Telling you that you should "move on"? When obviously you have tried your best all your life to carry on living, not give up, went to therapy, tried medication etc.?
Please don't lose your hope and carry on trying to get better. If you need to access even more therapy, try it, even if it won't work, at least you know you tried your best. You never know what may help you.
Don't be in any kind of contact with someone who blames you for not working. Always ask yourself what kind of person is that? Can you really trust their judgement? Maybe they are abusers themselves, and you don’t know about it? Maybe they can't understand you because they've never been through it? There may be a lot of other reasons why they are so cold hearted and blame you for something what's not your fault!
I really can't understand why and how anyone can actually blame a person for their health issues, be it physical or mental health issues. Nobody can choose how they feel today, sick or healthy!
OP do what you can, even if it's a tiny little thing, be proud of doing it! Carry on having short walks with your friend, I think is great that you do it despite all your struggles. You are a very strong person 🌹🌹🌹
