<human>: Can you give me a shortened version of the text?

My best friend is amazing, she's funny sweet and so caring but underneath it all she's so insecure. And not many people know it not even her own family. When it's come to guys she has always pushed them away. This new guy she's been with it's going well for her but I've started to notice little familiar things in her. 

She gets upset if he likes pictures of girls if he doesn't text her back for hours. He doesn't know this because to be far to her, she tries her best to keep it too herself. But at night I can hear her crying to herself and it's really upsetting me. He makes her so happy then she's left alone and she sees something that she doesn't like and her mood just drops. It's like she's terrified it will be taken away from her.
<bot>: Should I suggest going to get professional help ? Or can a person with insecurity issues not be treated because it's something in their own head ?
