<human>: Can you summarize the given text in a few sentences?

My sister passed away a few months ago, and my boyfriend of 2 years just ended our relationship. I called out my best friend of 7 years for sending terrible messages about me and she told me she doesn't have time for our friendship and dropped me. My parents are never proud of me even though I get good grades and have a job and I work hard for everything I have. I spend all my time alone now. I don't feel any motivation for life. Clearly there is something wrong with me because nobody stays for very long. I'm too shy to go out and meet new people because of my insecurities and I'm sure they would leave too.                   
I have never in my life felt the love i have given out.. I care too much and I wish I could stop.         
Someone help me to not fall apart. I'm dying inside. The past 19 years have only gotten worse, never better, so I don't believe in the whole "it gets better" bullshit. How can someone accept being unloveable?...
<bot>: I wish my life was over, everyone in my life leaves... How do I move forward from something like this? It feels impossible.
