I feel like isolating myself, but deep inside I am very lonely. What do I do?

Sometimes, it can be nice to reach out. You can try reaching out to somebody you feel comfortable with. Just try to hang out with them for a couple hours. It may make you feel a lot better :)

It's hard to say what /you/ should do; as many people experience this - but in different forms. The best option is to get yourself out there every once in a while, even if it does make you feel slightly uncomfortable. In the long run, it may be worth it. It's nice to have some time to yourself, but it's also nice to be around people occasionally.

Socialize. I completely understand that that probably sounds like the worst possible option right now and that the word itself might even scare you a little, it is the only way to cure isolation. Being alone is healthy from time to time but isolating yourself all the time is not a good way to live. Human beings are built for community. Please, don't be afraid to embrace it. It will take time, it will take energy but it feels wonderful once you allow yourself to open up to what's around you. Of course, I don't know your entire situation, so you can do with this advice what you will but please be safe, healthy, and stay strong.

You feel lonely, but company of other people is not helping you cure yourself. You may like to spend a little while alone, with you self, and learn about yourself. You could learn to live your own company, which would help get rid of loneliness. You may try new hobbies alone, read, write, etc. Find out where in your interest lies and learn to love yourself. You shall find that after this step, the company of others is sweeter than before.

It's never good to isolate yourself completely. Maybe you just need more alone time, and more time with friends at the same time. For example spend a few days a week doing things that make you happy, whether it's reading, gaming or photography, let yourself be happy with your own company. But then a few days a week also see friends, talk to people, surround yourself with people who positively impact your life and you will find being alone, and being with other people much easier :)

You should try to meet new people even if your nervous to do so, it will really help your lonelness.

Ask your family members for opinions and advice. Their experience can be helpful. Don't be afraid of judgement and criticism.

We do experience unhappiness when we feel unwanted and we want to make a place for ourselves by covering up ourselves under the impression we are not dependent on anybody for affection to prove that we are strong and worthy of being respected but in reality we don't want to be left alone the best option here would be to try talking to someone who seems to care and we are comfortable with but still one has to maintain some ego to feel respected and one has to be knowledgeable for supporting the ego factor.

Deep inside everyone is alone.The best part of our life is we being our best version inside,So don't feel bad for these things,Try to connect externally and maintain that lonely self inside.

I understand. I have gone through that too. Try making a goal to make one friend a day. It will help more than you think.
