I (18M) have been yearning for my boyfriend (21M) since I left for summer break and it's becoming unhealthy. How do I keep myself busy for 2 months?

posting on my burner, this might be long but I had a very rough second semester as a freshman.

For a bit of background on my bad decisions, I had to move dorms after a situation in a queer-themed dorm with a housemate left me targeted by everyone else (we all hung out). I spent my time with short-term hookups that only made things worse for my mental. I kept myself from social events or any sort of activity with friends. And more importantly, my grades tanked and now I went from a 3.1 to a 2.6 GPA.

Things looked better after I left the dorm and I was able to find new friends, I got therapy and reassurance on my dorm situation. I got a dope ass roommate, and I went out after being in my feelings for a while. I didn't stop being on the apps until I met my boyfriend. He let me crash at his place for the rest of the semester and not only was it less suffocating being away from my dorm but he is so communicative, so considerate, and SO loving to me on a real level. I felt so in control when I was with him and he motivated me to finish as strong as I could by the end of the year. Like, people I talk to in college always make me feel like I'm crazy for being emotional or compassionate but we click so easily when we talk- The only time we ever had an argument was when we were talking about pop artist drama. He doesn't hold any resentment for how I was before I met him and makes me feel so seen.

Anyways now that I'm done raving about him, I had to move back to my hometown once the semester was over and our goodbye was relatively simple, no tears and no heavy emotions, just "see you in the fall!" and all that.

The second I made it back home, I felt nothing but sadness not having him with me again. I expected myself to be okay being away from him but now I'm just sad all the time. I miss his touch and the way we would hang out, not to mention how our relationship is only 2-3 months old tops so I not only do I miss him (I feel childish saying this) I'm anxious that me not being super self-sufficient with a job or even my age will sway him away from me.

Obviously we still talk a lot and I'm more on my phone than he is, but I always see him busy with his life and his friends and he's honestly better in person than online. I feel like I'm obsessed with him and I find myself critiquing the smallest things, but I don't want to have my life revolve around him because that isn't sustainable for him OR MORE IMPORTANTLY for me.

So now I come here to ask as a gay bro to other gay bros, How do I stop this cycle of me being so deep in my feels? Any practices or things that help take your mind off of it or anything that helps you while you may be away from someone you miss? I've been trying to find a job to make some money on the side and a job (even though I have no experience) for when I get back since we'll both be more busy than last year, but a bit of advice from reddit never hurt nobody!

I really hope he doesn't use reddit-

TLDR: I feel very deeply and emotionally being away from my boyfriend after a hard year in college. He's busy, I'm not, and I'm kind of insecure that I'm not independent. How could I stop myself from yearning so much and do some good for myself before I return?
