Ah sorry. No I specifically meant birth data...day, place, time of birth etc not any information about you perse (though that can always help...sometimes I like to avoid that knowledge to avoid bias and potential cold reading).
That said, age 21 alone gives me a bit more to work with predictive wise.
Presuming you just turned 21 (a belated happy birthday) then you were undergoing Sun maturation (20-21). That age is important for the development of the Sun...it's fairly normal in that time period for a person to have things thrown at them that make them uncertain and throw them off track as their Sun "comes into its own."
I already looked at your Sun a bit earlier, but that just confirms it is actually activated at this time. 8th Lord makes breaks and changes, 10th is what one does in the world. Due to it's state and your age it is fairly normal to have the concerns you have and to have challenges to "standing up for yourself" and conflicts due to that. It is trying to mature the person's ability to "rule their own life" at that time.
Overall it is creating conflict due to the wavering and indecisive nature of Libra on the Sun, which does better in a more "firm, decisive" way. Changes in your path and what you do in life are probably inevitable (as it is also 8th Lord, and 10th lord of actions in the world is in 8th...8th causes breaks and changes).
Normally I'd advise someone to be consistent with their choices in that time period ...but in your case, as said it is probably inevitable change will happen.
So perhaps it's more important to realize that no decision you make is really truly "final" (there are many people...I'd even say most...who choose a major but then never go on to work in that particular major afterwards). But it's still important to make the best decision you can at that time and try and commit to it at least for the moment in order to make some progress. As well as stand up for your choices, if they are truly inspired, when the time comes.
That's focused even more, as 21 is the year 10th sign (which holds your sun and focuses on "career path" in the world) is activated.
21 is also the beginning of a new cycle of 7. It is typical for ending of those cycles (20-21 in this case) to be a bit troublesome comparatively as they break down the past 6 years that aren't going to help you properly in the next 7 years. So what you're losing was probably not going to be of much support in the future anyhow...I know that's not necessarily comforting in the moment though.
Ascendant (body) directs (by one degree per year) to opposition of Mars in the 8th. Saturn will be coming to square itself. Be careful to take care of your body this year...those could indicate some potential danger through accidents. Mars is lord of whole sign fourth (home) so perhaps that issue is concerned with what already happened since it's not the most exact timing method.
It's honestly not a chart for an easy, smooth life path. Due to the 8th house switch with the 10th, and dignity of certain planets. There will almost certainly be more bumps in the future and shifts to yet again uncertain grounds...
But you really don't have to be led around life by your chart IMO and IME. Some people do have it naturally easier though...you're not likely to be one of them.
