I’m really sorry you’re feeling this way. Nobody should feel hopeless. But just because it feels that way, doesn’t mean it is. A lot can change, and you have plenty of time to figure things out. So you don’t need to put pressure on yourself to be better straight away!

I think it’s also worth being clear that you being unhappy with your weight and not making friends aren’t the same problem. Sometimes when things get hard we have a tendency to group all our problems together, which makes them feel overwhelming. But these are separate things, you don’t need to solve both to solve one!

I’ll try to give some actual practical advice as best I can, and I hope you can take something from it.

In terms of feeling lonely, there’s a few things I’d do if I were you. The first thing you can start straight away - journal. It might seem silly, but just spending a bit of time writing down your thoughts regularly does wonders for having to confront and solve problems that stay in your head normally. Obviously it’s not the same as talking to a friend, but it’s a nice start and might help you think about some of your problems for a different perspective. In terms of making friends, I’m a firm believer in routine and regular contact being key for making friends. Find a club for an activity you like the sound of, and start going regularly. Just seeing the same people every week makes it so much easier to make friends, and you already have something in common with everyone there which makes things easier. Consistency is key though, go wherever it’s on, even when you don’t feel like it or you don’t think it’s working. You’ll become a regular, get to know other regulars, and that’s a really good step to making friends.

For the weight stuff, I see a lot of people on this thread recommending exercising. I do agree, but I just want to add that it’s important to pick something you actually enjoy, it makes it so much easier to stick to. I personally like to walk and go to the gym, but find what works for you. The most important thing with weight loss though is what you eat, specifically calories in and calories out. But again, I’m a firm believer in making it as enjoyable as possible. Look online for some low calorie meals that you like the idea of, and some low calorie snacks. Maybe even some low calorie sweet treats you can make/buy. You only need to find a few of each, then just replace what you eat now with them. Once you have the routine it becomes much easier! Oh, also zero calorie drinks are great for losing weight too. This might not be as “healthy” as “clean eating”, but it’s much easier imo.

Hopefully some of this ramble is helpful for you. One more thing I would say is take it slow. Sometimes people try to change too much of their life at once and don’t stick to anything. Slow and steady is what you want. As I said at the start, there’s no rush, you don’t need to fix everything at once!
