Is it possible to change how you feel about yourself?

Well, I have had times where the way I felt about myself changed.
And like you, from a very young age I felt like I was nothing and wanting to disappear into thin air.
Very deep rooted from childhood.
I made some very good friends eventually, who brought me up, showed me love and care I’d never had, and, for a short while, existing wasn’t so painful, I thought maybe I wasn’t so bad. I got a glimpse of health – emotionally and physically. But the old thoughts and feelings always find a way of creeping back in, knocking me down, digging their claws into me, telling me I’m a useless piece of shit etc etc.
I have never really put in the work though, (besides for determination – fake it till you make it type thing) so I think, maybe it is possible, with some intense therapy, going all the way back to the 4 year old you, working your way up until now, and it can take years of work, I’v seen other people do it, with results (I always think i’m a special case that cannot be helped) – but, yes, I think it is possible to change, it just depends how much work you are willing to put into it and how committed you are to it.. and also what kind of support you have around you.
You can start off by writing something good about yourself each day.
One thing, or one good thing you did. Even half a thing.
Because there will be at least one – if not many more.
You can’t be that bad. But you are feeding off all the negative thoughts, it’s habit. It’s ingrained in you – start changing that if your willing..
