@NeedAdvice1993,
You have several things going on here.
You talk about depression but why are you depressed? Its very important to examine this and in as much detail as possible because the solution is achieved that way.
I know you feel comfortable being alone but since you are depressed you shouldn't do this. The reason is right now you are your worse enemy, youll continue to spiral in your depression.
I usually tell people to remind themselves often a short simple phrase. "Things can't be bad ALL the time, its statistically impossible."
Things can't always be miserable, there are solutions, you just maybe need them pointed out.
I'm assuming here, do you live in a city/town that is not lesbian friendly? Because that's what it sounds like.
With your family. Even if they haven't fully embraced your identity. You should take advantage of the time you have with them. They won't live for ever. You might regret it later, wishing you had if you neglect this. Just be yourself, they are your family, they have no choice but to accept you.
You need friends, we are social animals and not having this input can leave you in a world you really don't want to be in. Which is inside your own thoughts. If you feel bad about yourself this becomes extreme without friends to distract you.
Maybe you need a cute girlfriend to get you out if your head. Someone else you can focus on. No matter how negative you feel about yourself, there is ALWAYS someone out there who thinks you are great. Just need to find them, its not hard but if you always hide a way they won't have a chance to discover you exist.
Dont worry about your debt. Just make it manageable. Pay what you can but why worry about it?
Find something that you are passionate about and pursue it. Some people say they don't have a passion but thats nonsense, they are just intimidated to admit what it is, fearing failure or judgement. Just start doing it and develope a dont care what anyone thinks about it attitude.
There is always something you can do to find contentment.
