We all feel like this sometimes. You will feel better in a couple of days and maybe after talking with the PDoc.

I too feel the same way, but the good news is that by recognizing it, you already have a good start. Then by looking for help which you are and have been doing then your in a really good space here to talk and write out your feelings and emotions!
Your going in the right direction my friend
Overcoming not falling victim to, a good goal
Be well

Yes it really sucks looking around at other people and realizing that you are not like them. This has haunted me for many, many years. I hope the pychologist can help you, but it will take some time. I sucks being so lonely, doesn't it?
It took me many years, but I finally came to peace with it. One day I just accepted the fact that I am different. No, it didn't solve the problem, but it did help. I wish you luck, my friend.

What others see and what we feel can be so different and often times the furthest thing from the truth. You are no freak and certainly not alone in how you have been feeling. Give yourself a chance within your boundaries of comfort to stay engaged with others if even as you share with us here. I'm hoping you have a good visit with your doctor tomorrow and hope you will keep us updated. You are not like anyone else because you are way more special :)))

Bridges,
It's not your imagination that the energy is off in grocery stores. It is very off; and I just thought this yesterday So, don't blame yourself as though there is something wrong with you for feeling this way. Since everything that has happened, and there have been riots in my area, going out has become risky and that is why the energy is like this. We had a curfew for a while due to this, and there was real damages to some of the store fronts. There was a rage episode outside of one grocery store yesterday. Still, I'm glad you are going for help; it should assist you regardless of whether the discomfort comes from within or without. Good luck.

Also, maybe this is outside the scope of this chatboard, but maybe you have an attuned sixth sense, a gift for sensing energy. I know this is woo-woo, but I do believe this to be the case. I often wonder if people who feel like they could be "mentally ill," may have other spiritual senses. Some people think that's a load of garbage, but that is OK, I realize my status as an outlier; I've been told as much by others and I love it! I can say I like or even love me for being weird! There are a lot of benefits to it, once you feel better you can help others. Your biggest "liability" could be an asset.

When it comes down to our individual selves, I do not think anyone can truly understand another like they understand themselves (heck, some people don’t understand/know even themselves sometimes). For one thing, we all have separate bodies that separate us from another mentally/physically and considering different language, culture, community, background etc… we are some sense alone in our own unique life/experience. Even if two people go through same experience, although they can relate, how these experience are registered/felt won’t be exactly the same as another. But having said that, you are not alone in being/feeling alone and not alone in experiencing these typical human issues as although we are all unique individual, we are afterall all human being. Human lives are typical and limited and issue any human being can go through in one’s life is all too obvious (money, job, health, birth, death, relationship etc..). We are uniquely alone but that is true for everyone so you are not alone.
World population is close to 8 billion, there will always be some people who will understand you and some won’t. Whether or not one particular person will understand you throughout rest of your life will highly likely no as everyone goes through changes and the person you met before won’t be exactly the same person few years later and same goes for you as well.
You should also be aware that things are different now (with covid-19 going on) so it’s no surprise people will act differently. There will be more anxiety and stress, people are losing job, get sick and some pass away. Before there was some level of certainty and constant living but that pattern has changed due to this sudden pandemic. You need to numb your sensitivity (lower your antenna) a bit during this time as it won’t do you any good. You don’t need to feel everything, instead, focus on your inner world and find balance/peace.
Some people do have long lasting relationship, but don’t assume it’s easy peasy. Things can be very different than it looks on the surface (everyone is different, what works for them, you might not want it in your relationship) and even if it isn’t, it’s a constant work for both party involved to make it work in long term. It’s really easy to underestimate other people’s relationship from outside and you are being very dreamy (wearing a rosy coloured lenses) about it, ignoring/overlooking the complexity of relationship and issues that can easily arise from it.

I am sorry you feel this way. I think so many people are struggling with the changes and maybe their energy is off. You were put on this earth and a divine reason. You are created wonderfully and beautifully, even if you do not feel it at this time. How did the meeting going with the psychologist? I am glad that you are speaking to you. I am praying for you.
