Girls please help me

L

I met up with someone on tinder and we had sex and I really liked him and I honestly thought he was really into me (not in a vain way, he was just so nice to me and very complimentary). He told me he didn't think we were the right fit. I'm devastated. My ex who I went out with for four years broke up with me in May. I just feel like I'm not good enough for anyone. My confidence is so low. Every time I see a couple or think about my ex or the tinder guy (obviously I'm trying not to think about them but it happens all the fucking time) I feel crushed. I feel like no one will ever want me

😭😭😭😭😭
