Hi @outlander ,
As @Shaz51 said, its a tough one. Real hard.
Everyone has there ups and downs and your family should try and support you whatever you are going through. It sounds like your pop makes it more diffucult than it might be otherwise. I give him a pass as I'm pretty sure he doesn't really mean what he says a lot of the time.
I don't think being in a bad mood, sad or watching tv says anything about you as a person. I would ignore it and focus on what you want to get out of each moment and day as best you can. What do these critical people do to help you or others? I bet its not anywhere near 1/2 of what you do.
Your mum and partner sound a little callous to Me. I know that most people don't understand how hard and challenging living with or even being stigmatised by MH issues is. It's hard to change that mindset if they are not open to change or willing to consider things.
My limited and not so helpful suggestion is to try and take care of yourself mentally and phsyically as best you can.
Having your guard up 24/7 at home must be draining on both fronts. I would try and relax on that front and recognise the zillion things you do rather than listen to others influence what they think you should be doing.
We are all different. Try and recognise the small wins that you get.
I don't know about acting happy all the time.. I can only say that trying to be upbeat and looking to see the positive in things may help interactions. Being honest and vunerable is hard. Anyway, take my thoughts with a grain of salt, i'm male and relationships aren't my forte.
You are an awersome, caring person with a kind and good heart and that should count for a whole lot.
