Kasperblue, I am so sorry you are isolated. I am very fortunate to have a few close friends, but overall I do have an issue with making friends and often end up isolated or isolating myself. This has been a problem for me since I was a child and often treated as different and not included or even bullied. As a result, I expect to be rejected I think and also have social anxiety. I think this limits my ability to socialize and makes it hard to connect with others. I am only now just realizing how much my view of myself is affecting things. For example due to social anxiety and assuming no one wanted to be around me I avoided a function at a work conference, then ran into people who invited me anyway and had a good time. My mind was using past experiences to make me feel negative about the current one.

I am not suggesting these are issues you have, but I wonder if this problem with isolation is something you can examine in therapy to get some feedback. Sometimes we do things without realizing it that affect our interactions, or can be meeting people who aren't quite right for us, or if we are not doing well mentally in general this can make relationships difficult and we may need to work on that first to build and maintain healthy relationships.
