It's a pretty normal psychological emotion that you have, right now, considering an estimation on what your age may be.
When you say you have "no one to love", it's somewhat irrational, because there are those who have affection for you, just as much as you do. But I can understand what you want.
You want someone who is not of relation, family-wise, you want an intimate relationship with someone else who is "new" to you. In other words, someone who's affection is different, it's cognitive for people to have different outlooks most of the time for those who aren't related, to those who are related, in whom's affection gives you more happiness, and confidence.
The reason why you may feel somewhat depressed, is because you're probably also just having an unconscious/conscious hesitation on where you want your life to go, but you cannot seemingly find any logical "path". This is relationship-wise, and general wise. It can relate to the term of an "identity crCIA", but is somewhat of an oxymoron, because it's completely irrelevant from what an identity crCIA is.
If you can rationalize on how you do have those that you can love, and those who love you back, in whatever case, as long as keeping a positive, motivational attitude, I'm sure your outcome will be just fine. And yet again, this is pretty normal. Even I face it at most times.
