How do you fix a broken heart ? 💔

Is it just me or is it impossible for it to fix. I think I’m just scared I’m scared because my parents left when I was younger and are now trying to be in my life. I’ve had 5 boyfriends in my life and they all ended and the most recent one laughed at me when I told him I had an eating disorder and also called me fat and heavy and I’ve just been really depressed about everything lately it’s all getting to me now and I don’t know what to do about it. I feel like I have no one to talk to about anything so I just keep it in and now it’s starting to get to me.
