Don't believe this: your value increases with people's appreciation and your worth decreases with people's disapproval.
Instead, focus on what's really essential in life. Firstly you begin establishing honest connections with a few mentally healthy individuals and a few pets and plants. To do this you need to declutter your life from removing useless garbage. Throw away those people who do not bring any value to your life except just socialize. They are a nuisance in your phone list.
Throw away all articles which you don't use in every day life. Instead direct your focus on truly essentials like your family, your life time goals like musicals or mountaineering.
