Heya!
I think it is really important to work on yourself before you try and start dating.
You probably won’t address all your big insecurities and such before you start dating but dating can help with a lot of these things to! It can help you learn more about yourself and you can learn whatever it is you’re looking for!
In my personal opinion I think if you don’t have the headspace to potentially invite someone into your life then maybe hold off a little bit.
