Just know that you don't have to put up with others treating you poorly or taking advantage of your kindness. It may not seem like it right now, but with both platonic and romantic relationships, there are people out there who will treat you right. There's never just one option for a friend, partner, or acquaintance. So, if there are people in your life consistently making you experience negative emotions/thoughts, distance yourself from them and move on to better things.
Love doesn't have to be romantic, It can be platonic, familial, Any kind at all As long as there are multiple hearts involved, And they beat for the sake of one another, That is true love
