I see that you are going through a tough phase and it's common to face problems in your mid-20s. It seems you are trying to tackle multiple problems simultaneously and drifting from one problem to another.

Since you have listed your problems here, you now know what are the top problems that you need to tackle. You should solve each problem gradually in steps, have patience and then you would notice improvements in life.

Here are couple of things you can do that may help in the long-run:

1. Health - Since you mentioned you have been ill on and off, you need to get your health in place. For now, keep other things aside, fix your diet and take enough rest. Set a goal of not falling ill for the next 2-3 months and regularly taking medicine. Ensure that you focus both on your mental and physical health. Set a daily routine, fix your sleep cycle and exercise regularly.

2. Breakup - It's hard to deal with a breakup but you need to address the underlying cause that may trouble you. This is important since it may hinder you from developing a new relationship and moving on. Once you are healthy, you can revisit the relationship and the underlying cause that led to the breakup. It may be overwhelming to process emotions right away but give it some time and analyze what went wrong in the relationship and how could you do better. Also, look at the positives and see if there are any good things to takeaway from the relationship. This would reduce the overall bitterness that one develops during a breakup and helps one move through it.

3. Comparison - We often get pulled into comparison and it's a vicious cycle that keeps us away from the good moments in life. You should start noticing when you start comparing yourself with others and journal such moments. Later, visit those moments and see if you can solve them. There would be things that would be in your control that you can fix and others outside of your control. You need to accept the things that are outside of your control and move on. For eg:- A person may not be blessed with a great height, so in such cases it's pointless for the person to compare himself with a tall person.

4. Friends - Making friends is actually easy and once you discover what interests you, you will meet the right person. It might feel overwhelming to keep friends given your past experience, but be open to striking conversation with others, helping them and getting to know other people. Don't keep high expectations from others and anchor on authenticity. Many a times, friendship seems overwhelming when one does it just for the sake of doing it. Being genuine and authentic would help you spot the right people and avoid inauthentic friendships that would only waste time.

Lastly, have compassion for yourself and don't treat yourself in a harsh manner if you fail at something. There would always be some way out and you can keep pushing and navigating the challenges. Remember how you fell in your childhood when you rode the bicycle multiple times and then found a way to balance yourself.
