missing out

Lately I've been kind of down that I feel like I'm missing out on a lot. I'm 20. I went to tech school at 17 finished at 18. I'm getting out of that field, I started community college, but I'm finding that's not for me. I decided to go to cosmetology school next year. I'm dead set on it. Anyways I live with my boyfriend, I've been with him for 3 years. I honestly don't have any friends besides one and we don't even see each other much. I work two jobs so I am pretty busy. Most of the time I'm content with my life. But lately I kind of feel I'm missing out on really being my age. I see everyone from high school in college at pa looking like their having the time of their life. Couples taking cute halloween picture together. Again people my age traveling to amazing places. Just really living life. It just makes me feel down because I don't have friends, my boyfriend isn't like romantic or affectionate at all that he rarely even takes pictures with me. He doesn't like drive far, scared of flying so we've never traveled anywhere. And now we have 3 dogs so if we did it'd be kind of hard to find someone to watch them all. Idk it just kind of sucks. I thought I had my life together then I came to I hate what I'm doing for work, I found what I want to do now but it's just going to be a long time before I'm done with it. And Idk I love my boyfriend, that I have a good job now, but I'll soon be doing what I love, we do good for ourselves, we have 3 awesome fur babies, I have one good friend even if I don't see her a lot. Just sometimes I wish I could live more like a 20 year old should, not like I'm 20 years older.(no offense).
