I am all alone ˙◠˙

For the 1st time in my life I am completely alone :( in less than a year I have managed to deplete my small social circle with some ppl I even knew from preschool (in 2 months I begin uni) to absolute 0 and my mental health has been declining for many reasons and some of them I can't even identify, it's been better lately and I could be talking about my struggles for a while but maybe I'll keep it for another blog or even 4 myself. The point is that I never learned 2 love and appreciate my own company and myself and until a while ago the thought of being alone frightened me, and I hated and felt really guilty if I hadn't met someone or done a hobby/activity outside for 2-3 days, and to a little extend I still feel that way, but the difference is that this is my norm now....I only have my very lovely girlfriend which showed up like a month or 2 B4 all this started happening and I don't believe that it's her fault or me only caring about her out of nowhere, I want 2 believe at least that it was a combination of my few incredibly consistent friendships deteriorating and falling apart bc I slowly realized, mostly with some thoughts or opinions from her but also my own judgement after these opinions (I swear she isn't manipulating me) that these friendships weren't exactly healthy and that I was also withdrawn and sad... And now, a very changed person and more mature and also about 2 become an adult, I find myself utterly lonely with nobody 2 hangout with or talk 2 except 4 her... And even now she can't even really contact me except from her laptop bc she lost her phone a couple days ago coming over 😬😬 but I helped her relax and she helped me too and we had such a fun and beautiful and peaceful time after we calmed down and she lend me the Korn self titled CD which is the 1st time some1 lends me a CD! And it's cool, I listened 2 it today! But the point is that after noon my day became really quiet and lonely, I only have my cat which I occasionally let into my room and I only live wt my problematic mother which I woke up early and had to figure out uni payments with and it was annoying, I have even lost partly feelings 4 her but that's a very big story which I don't plan on sharing at least 4 now. Im not sure what to do, I can't be seing my girl everyday bc that's tiring and she has a couple more friends and under way better circumstances also she's busy with pilates and life, like family, and even vacation on August so I'm fucked.... Especially when we were planning a 1-2 week vacation together to my home on the countryside but we decided 2 cancel bc life is weird lately so yeah.....no friends, (partly) no gf, and no vacation and if I go somewhere it's going 2 be on said countryside but wt my mother so fuck me and also 4got to mention, we will have to part ways with my gf in September and it's painful 2 think about sometimes and especially after my circumstances... But I know it isn't going 2 last 4ever, bc I will be moving to a whole different country, in a "student city" that also has Greeks like me in the uni and maybe(?) in general but not that many. 4 now tho..... What do I do? What do I think? I have even lost interest in my hobbies like basketball and skate (not that much on skate but it's 40 fucking degrees here and I have 2 travel to the edge of the next city and be practically alone just 4 a sess on the skatepark) and also I don't workout anymore, even right after my comeback on it, but I do still draw! so THE MAIN POINT OF THE BLOG: do y'all have any advice or even thoughts or opinions? And if anyone read the whole thing, thank u, ur a legend :)
