Self acceptance

I came out as bisexual around 2 years ago in which I have had a girlfriend for the last two years but after all this time I still don’t think I’m comfortable with who I am and that I’ve never full accepted myself, she believes I may have internal homophobia like I’m not comfortable and I don’t like who I am, I don’t like being affectionate in public in anyway because I feel eyes on me and sometimes I don’t want to be seen as who I am we’ve decided to take a break so I can focus on myself and my own self acceptance. I’m looking for a way to overcome this so I can do things like hold hands in public
