How do I start dating?…I’ve always sucked at dating. 28f….

I’m 28 years old & I’ve never had a boyfriend. I’ve always had a hard time getting men to notice me. I don’t understand what I’m doing wrong. I’ve been to therapy but nothing has worked. Everyone of my friend’s are in a relationship. I’ve decided to go on a dating app how do I do this…..<br><br>Edit: I’m going to start by updating my hair, nails and makeup. Next week I’m going to get my hair, nails and makeup done. I’m going to go on a calorie deficit to start weight loss. I’ll start this Monday. Lastly I’m going to join a gym to meet people. Once I feel good about myself I’ll start creating dating profile.
