I wish i was more confident

I'm 40 years old and been single for about a year now. I actually enjoy being single but I would like to share my life with someone and be in love again. Here's the thing, I match with someone on tinder or bumble and start talking but then I'll shut it down. Mainly because Im too nervous to meet them because I don't like my body shape or I think I'm not pretty enough. I know what you're gonna say "those apps are mainly for hookups" I already know this and I'm not looking to instantly find the love of my life on them (although you never know) but just because I'd like a relationship doesn't mean I have to be a nun in the process 😉 and at my age there are more men wanting to settle down than men in their 20s or 30s. Another thing you might say that if they don't like me for my body shape etc then they're not worth it. This is very very true! But it's not really their reaction that worries me, it's more me and my problem. Like I would be so self conscious and over think they they don't like even if they did. God I sound like I need a therapist lol. I don't though, but what I do need is a bit of self boosting tips and advice please if anyone wants to help? I feel like I'll never get my happy ever after
