To begin, you are NOT doomed to never have a relationship. In fact, you have Jupiter (the planet of luck and expansion) in your 7th house (house of long-term relationships and partnerships)! And it is in good aspect to Venus! You certainly have potential. Now, Jupiter does square Uranus, which can make for unstable relationships at times (if you aren't careful about choosing what type of person you date). Your 7th house planet squaring Uranus can make relationships be either very quirky and bizarre (in a good way or bad way) or it can cause for the types of relationships that end as quickly and suddenly as they started.
Venus in positive aspect to Jupiter and Jupiter squaring Venus makes me wonder if perhaps you haven't had several dates over the years, but they simply never panned out into serious relationships? Or maybe you meet girls you like and you begin talking and being friendly, but then it just goes no where...it just kinda ends?
Now, here's what's really troubling you: Venus square Saturn. Saturn represents delays, blockages, difficulties, and hard lessons. It's squaring your planet of love. Meaning relationships will come very slowly and with difficulty. You will feel like you have no luck with relationships or in love. Especially when it comes to finding a long-term or stable (meaning one that doesn't consist of breaking up and getting back together) partnership. You also have Venus square Neptune. This can mean you tend to idealize certain women or have unattainable/unrealistic expectations. Maybe you fall for women you can't have (perhaps she's married, lives too far away, is famous and you've never met, etc.) or you have this picture of a perfect mate in your head (that doesn't exist in the real world) so you refuse to give anyone a chance if they don't fit that ideal.
So yes, with the Uranus Square and Venus squaring Saturn, that is why you're experiencing such delays and blockages in love. But will you have a relationship? Why not? You have Jupiter in the 7th and in positive aspect to Venus in the 5th house! Maybe you just need to get out a little more when you can and approach some women! It'll be difficult for you at first, definitely. I know you're shy and perhaps never having had a serious relationship makes you insecure about approaching women, but you have Jupiter in Leo in the 7th in good aspect to Venus in Gemini in the 5th, you definitely have the charm in you.
You also have Capricorn as your rising sign, so you likely come off as very serious and independent, so when you do go out, be mindful that some lady might not understand your quiet demeanor as you being shy, because with that Capricorn rising, you may just come off as very serious and uninterested. Try to be friendly and social! You may even run into a few embarrassing situations at first, but everyone has! Maybe even try online dating (from reputable websites, not Tindr--that's for hookups or short-term relationships, try something like eharmony or something).
Also, Chiron in the 4th. Pain coming from the family or childhood. Your mother suffered a terrible death, I'm really sorry. Chiron represents wounds that never heal, so in your chart, Chiron in the 4th is the pain of losing your mother. And your father falling ill and you having to support your family certainly cannot be easy on you either. But the fact that you are family-minded will be very attractive to a nice woman
