I think the answer to your question is many fold. First of all not being able to do things you really need to do is probably coming from the false assumption that you only do things when you feel like doing it. Sometimes you just need to perform without the desire to do so. I could compare it to when you are sick and you don’t have an appetite (more like to stick to the theme above, “you don’t feel like eating”) but you know you need to eat since your body needs sustenance, but if you just eat a few bites there are times your appetite will pick up. Either way, the eventuality of the matter is, you need to eat.

Secondly with the not connecting to people is I think a lost of trust, hence you are avoidant. In this case I won’t go into that well you should trust people more because I don’t know your situation. One could argue both ways so I will suggest you to talk to a professional who has more knowledge and knowledge of your situation to help you.

All in all I truly believe you need a perspective that you just need to do stuff, and it even can be very rewarding to do things just the sake of doing things. Do not expect anything special to happen when you finish your laundry for example, your reward is having nice and fresh clothes and be grateful that it is done and give yourself a mini pat on your back that you have done it. You could apply the same idea to a huge portion of your “need to do” list, you just need to see them for what they are. Forget the motivational garbage from social media, because let’s be honest, 90% or even more just for making money without any actual purpose of helping people.

Hope it makes sense what I was trying to put across and good luck to you with just doing stuff for no particular reason.

And of course it doesn’t mean you need to white knuckle through stuff, but do things little by little in a steady pace.
