SpoilerWhile I personally hate therapists, I have seen many, I truly believe that they can help. If at first talking doesn't help, short term (or long term) medication can help, that's something to consider.
I went through a very difficult period in my life where someone constantly told me I was worthless and even though it was 10+ years ago, I still struggle today with the feelings, especially since the "abuse" happened when I was young and impressionable.
I hope you find the help you need and are able to work through whatever you're going through. <3
I've always personally wondered about therapist (thanks to Arrested Development I think of a different name for them, lol) because it's like "how would talking to someone professionally be a different experience than talking with someone who isn't a professional, is it just paying to have someone listen to my problems?" Of course it's also a "don't knock it until you try it".
It's weird, it's not even like my childhood was filled with instances where I was told that I was worthless, being constantly second guessed or even belittled, etc. it's probably more of an abandonment issue that causes me to feel the way that I am.
At the end of the day I guess all I want is to be reassured that I'm wanted and that I matter
