You are not wearing a t-shirt where it says: "I live with my parents and I am 35." When people meet you, they don't know much about you. They'll have some impression of you, but not that won't be too accurate or embrace all aspects of your life.

Indeed, a part of your problem can be easily solved. I don't see how you cannot buy a clock. If you manage to work just a little, you'll get the money to buy a Timex (which look acceptable in many cases).

In the same way, if you work a little, you'll be able to rent a car for a weekend. It will make you feel better, but such things won't change your life, of course. But, if that's what you wish, give it a try. You'll be able to travel around and see something new.

The same applies to clothes.

Obviously, you'll need working a little bit on your social anxiety.
