Book suggestions about self love and feeling like you’re good enough for people.

After losing my grandmother at the start of the pandemic, my whole world turned upside down. She was the only one I could really call on for support. I just feel like I'm existing right now. I've always been a high energy person and I know that can be a lot to handle..I feel like I get on everyone's nerves 90% of the time. I feel like people see me as a an annoying little brother they can't get rid of…is there a book to help with any of this? Idk if any of what I said made the least bit of sense…..l'm just tired…tired of giving so much love to always be forgotten about…
