Too fat to date?

I haven't dated anyone since I split with my first and only boyfriend, I've been asked out by a couple of guys but I just don't know if I can go through with it. They might not think I'm that exciting in person because I'm a little shy and reserved, it takes me a while to feel comfortable around some people and truly be myself and it's backfired on me in the past when someone said I was boring/didn't make much conversation. Also they might think I don't look like my photos because pictures are all about good angles. I personally don't know if I can go through the process of going on a date with someone only for them to turn around and say maybe I'm too overweight for them or too dull. Please I don't want any hate for saying I'm insecure I know I'm insecure but I'm working on it I mean can't I go on casual dates whilst work on myself. There's just this paranoid feeling/worry about dates with people
