Have you ever had a weird feeling about something, and you eventually still followed it through? Maybe felt uncomfortable with someone, but you still entered a sort of relationship with them. The chances are that on the long run you would wish you had stuck to your initial thoughts about them and paid more attention to your feelings.
Our feelings matter, because at a time when the whole world, yourself included seems to think everything is alright, your feelings and reservations might just be saying the opposite, and this will be the actual measure of what you honestly believe and not just following what everyone expects you to. You need to remember that it's okay to feel, even when your feelings might not be shared by anyone else. Your feelings tell you a whole lot about what you think and what is going on with you. You owe it to yourself to pay attention to how you feel.
Regardless of what you think, on the conscious level, the measure of what you believe in your subconscious is tied up into your feelings, and they need to be expressed. If everyone else ignores your feelings, or make light of it, belittle it in any way, it's time you make them a priority and ignore everyone else. If you are feeling sad, even when everything seems to be going right for you, do not push these feelings aside or feel guilty about them. You should rather explore these feelings to the full point you can, see a professional if possible and deal with the causes of your emotions, till you get them resolved.
A lot of repressed emotions, fears, unresolved pains, grievances, the past hurts that should have been forgiven, even discomfort, end up in total or near disasters for the persons involved. Depression, anxiety, abuse, sickness, sometimes suicides arise from repressed and ignored feelings, which eventually manifest themselves in some violent over the top way at a point when things appear calmest.
It's okay to be sad; it's okay to be scared, it is okay not to like someone, you do not have to endure a relationship of any kind whatsoever because you want to make someone else happy as opposed to paying attention to your feelings and misgivings. It is fine to feel happiness, joy, excitement, and silliness if you are in the presence of someone you care about, and it's okay to be giddy about a new achievement no matter how small. It's okay to revel in these emotions and not try to suppress them or act all matured and grown up or try to appear politically correct.
If you ever feel the need to repress your feelings or ignore them for any reason whatsoever, or because you want to make any person or persons happy with you, then maybe it’s time to change your circumstances and the people around you. Feelings matter; pay attention to what your senses are telling you because they are telling you what is going on with you, they are telling you what is truly important to you, and you have a responsibility to pay attention to them.
