How do you love yourself? How do you stop the negative thoughts about yourself?

Not easy they are always there, unless you're a sociapath
Go easy on yourself
Because you care means you're a good person

You might try to determine the source of them.
Do they come from some childhood experiences, that you can now dismiss as being invalid?
By the age you've now attained, you can make some sound judgements on your own strengths and weaknesses, and can tell monkey mind to shut up.

That's really a tough one. I've been asking that question for a long time. A lot of people give me a lot of answers, but nothing really seems to work very well.

Constantly talking back to the negativity.

Daydream a better life

In all honesty I don't

I give my butt a spank and say "you hot, you da shit"

Just keep those negative thoughts pushed deep down.

Sometimes that is so hard to impossible.
