Words of encouragement?

So I’ve been feeling down lately. I’m not sure why but I’ve been getting distant with a group of friends cause they have their own thing going on so I just let it be. I was noticing that everyone has a close person such as a boyfriend or what ever the case may be. I haven’t dated since I got my heart broke 2 years ago. During this time I learned how to enjoy my own company and I know my worth but then I think “am I good enough for anyone?” I start thinking about my dad who never was a father to me, so if he doesn’t genuinely love me than who will? I’m not sure I just have been feeling like I’m not fitting well anywhere.
