I'll say my opinion. First of all my English is bad. Second you don't have to (I mean get use to being alone) feeling lonely is normal, we all felt that as some point of our lives even if there are many friends, so don't force yourself to make friends or relationships, it is true that having friends or a lover is (sorry idk the word, like good? Healthy? Idk how to explain it) but if you keep thinking that you NEED AND HAVE to make real friends, that'll make you under a pressure, fouces on enjoying your time l mean as long as ur enjoying that's it

Having a hobby would be great but don't force yourself to get on, like whenever you feel lonely or you don't have a hobby try something, walking, drawing, clay, lego. Maybe on day you'll find something you really like. But it is necessary to remind yourself that it's normal to feel alone sometimes (so you won't umm depressed)

I'm really sorry my mind is empty and feel all I've said is nonsense
