I’ve had a low opinion of myself for as long as i can remember. I’ve always hated myself and can never feel proud of my achievements no matter how big or small they are; im just “oh i did that: cool!” And be on my way.
How do I see myself as a human being worthy of love instead of a personification of human garbage?
Work on your negative self-talk.
Each time you remember something and cringe or insult yourself, you overwrite that memory with you feeling shitty about it. It’s a terrible feedback mechanism.
Instead, laugh at your silly mistakes, celebrate your successes and failures, and forgive yourself.
It will take a long time to unwind the stuff you have done to yourself, but this is one technique you can just start doing - recognize when you are beating yourself up and do a little better.
